John Dowson Posted October 16, 2023 Report Share Posted October 16, 2023 Looks like there may be a locking issue, which I will look at in a few days, when I get back home. However, your log shows that lvars are still being created after the intial lvars have been received. For complex aircraft, you need to allow more time. I suggest you increase the value of the WASM ini parameter LvarScanDelay - from the Advanced User manual: Quote LvarScanDelay=5: the delay in seconds between when the Ready To Fly stage is reached and the initial scan for lvars is performed. It is recommended to increase this if using complex aircraft or airliners as it can take a while for some lvars to be created for such aircraft. Note that lvars created after the initial scan will be found and pushed to clients if the LvarScanFrequency is non-zero. I suggest you start with a value of 10-12 (seconds) and increase if you still get issues - or increase the current value by 5-7s if you have already changed this. Also note that you should set this in the FSUIPC_WASM.ini file located in the WASM persistent storage location, not in the one under your Community folder as this will get overwritten (and therefore reset) the next time you update. See the WASM section in the Advanced User guide for details. John Link to comment Share on other sites More sharing options...

John Dowson Posted October 16, 2023 Report Share Posted October 16, 2023 Why don't you try reading the documentation.... Quote Parameters found in location 2 (WASM persistent storage) will take president and overwrite any parameters found in the first location. A default ini file is installed with the WASM and can be found in location 1. It is recommended to leave this file as is, and copy to your persistent storage area and modify as and when needed from there. Link to comment Share on other sites More sharing options...
Fragtality Posted November 11, 2023 Author Report Share Posted November 11, 2023 Did you find a Chance to look into this? Still is an Issue, even with a LvarScanDelay of 10. FSUIPC7.log Link to comment Share on other sites More sharing options...

Not yet, but I will add another lock on sending calc code when lvar/hvar updates are being received in the next beta, which I am planning on releasing in a couple of days. 12 minutes ago, Fragtality said: Still is an Issue, even with a LvarScanDelay of 10. Increase it further - your log still shows lvars are being discovered after this period, and you are getting the new lvars continually pushed. You want to set it to a value where most, if not all, lvars are found on the first scan. Try 15 seconds, and if you are then still getting new lvars pushed, increase further.

John Dowson Posted November 15, 2023 Report Share Posted November 15, 2023 Did you try increasing the LvarScanDelay further, and if so, did this prevent the CTD? I have now added further locking in the WAPI to try and prevent this - please try the latest beta available in this thread: If you still get the same issue, can you show me a log file from a CTD when you have WAPI Trace logging as well as Lua Plugins logging (not separately!!) and Event logging activated. The file will be large and may need zipping. John Link to comment Share on other sites More sharing options...
Fragtality Posted November 15, 2023 Author Report Share Posted November 15, 2023 Yep, even with 15 it happens. Will try the .26 Beta the next Days, thanks! 🙂 Link to comment Share on other sites More sharing options...
Fragtality Posted November 24, 2023 Author Report Share Posted November 24, 2023 It happened again - I think I found a way to reproduce: When I switch from another Plane (e.g. the Fenix) to the 787 (so the Lua-Scripts in Question get executed), FSUIPC will freeze. The Logs attached have not the required Settings. I'll try to reproduce it with the required Settings in the next couple of Days. Btw, is it normal for that Beta-Version that Applications from the [Progams] Section are started when the Session is Ready?

Fragtality Posted November 25, 2023 Author Report Share Posted November 25, 2023 Wilco. To be honest, I never had any Problems with READY. In fact it also worked perfectly to start GSX/Couatl as a Workaround for a GSX Bug. I use it for my own Tools (FenixQuartz, Fenix2GSX, WorkingTitle2GSX, DynamicLOD) and it was just perfect. Is there any Chance to get that Behavior back? Link to comment Share on other sites More sharing options...

From the Advanced User guide: Quote READY - delays loading and running the program until FS is up and ready to fly, and FSUIPC can supply valid data through its IPC interface. (This parameter may, of course, result in the programs being run in a different order to that specified by the Run number) You said: 19 hours ago, Fragtality said: Btw, is it normal for that Beta-Version that Applications from the [Progams] Section are started when the Session is Ready?

No - remove the READY, you don't seem to want to use this, so just remove it. John Link to comment Share on other sites More sharing options...
Fragtality Posted November 25, 2023 Author Report Share Posted November 25, 2023 Hmm. So either I did not found a reliable Way to reproduce the FSUIPC Freeze, or 26g had fixed that. Let's hope some long-term/normal flying Tests show it is the latter 🙂 Yes, you're right - I don't want READY anymore 😅 Even though my Tools don't have a Problem with that (they're designed to be even started before the Sim): Would it be possible to have an additional RunIf Option in the Future - maybe let's call it "PROC" or so. It would start the given Program when SimConnect is ready to process. Link to comment Share on other sites More sharing options...

If so, why not just add a delay? There is no Problem currently, that is right. But as I wrote, the "bugged READY" was a great Workaround to Auto-Start GSX when it had Issues. So that "PROC" Option could be a useful and general Tool for Applications which have Problems to be started when the Sim is non-read or semi-ready. Also: starting Programs which can't do anything meaningful yet (because SimConnect won't be ready soon) is not exactly perfectly reasonable also 😉 Yes, there is Delay and I'm using it also. But what is the Value which would work in any Setup? In my Setup even 60 is too less. Maybe for others it would be too much. (Background: my new Installer for my Tools can setup Auto-Start via FSUIPC for the User. So I'm thinking about what Delay if any would be appropriate as a general-for-any-Setup-Value) But yeah, there is no real Problem (currently). I just would find it more elegant to being able to auto-start a Program when SimConnect is ready to process. 🙂 FSUIPC7.log FSUIPC_WASM.log Link to comment Share on other sites More sharing options...
John Dowson Posted November 26, 2023 Report Share Posted November 26, 2023 Can you show me a log when you get a hang using the following version, where more logging has been added: FSUIPC7.exe Just use WAPI Debug level logging, not Trace.

John Dowson Posted November 27, 2023 Report Share Posted November 27, 2023 Well, that last log has thrown a spanner in the works... What was the issue - did FSUIPC hang? Could you access the UI? In all your previous logs, the last line logged has always been: Quote 187140 [DEBUG]: Calling Lvar CDAs loaded callback function... However, this time this is the last line logged, out of the blue: Quote 216265 [INFO]: SimConnect_Close done And I can't see how that can be logged with no other log message indicating why it was closed.... This is all very strange and I am at a loss as to what could cause this.... It would be useful if I could see a SimConnect log file. Could you configure to generate one - see Also please switch back to WAPI Trace level logging, and show me the files again, including the simconnec.log (it will be quite large and will need zipping/compressing, and still may be too large to attach....). I have also noticed an issue in the WASM from your WASM log. However, this does not cause any actual problems, but I will correct this in the next release.

John Dowson Posted November 27, 2023 Report Share Posted November 27, 2023 I have just re-read this thread and it seems the issue has changed since the initial report. Can you confirm that the issue now is that FSUIPC7 seems to hang, and that there is no response from the UI? If you kill and restart, does it then work? Do you only get this issue when GSX is running? How frequent is this issue, both when GSX running and when not? Do you see any events (warning or error) related to this issue in the windows event viewer? I am going to run some extended tests in the debugger to see if I can catch anything with this...

Since both FSUIPC and GSX are started via EXE.xml, both always run together. 59 minutes ago, John Dowson said: How frequent is this issue, both when GSX running and when not? Well, everytime I want to start a normal/real Flight-Session with a 787 Aircraft (respectively when FSUIPC runs the WT787 Scripts). Like stated, GSX runs always.

John Dowson Posted November 27, 2023 Report Share Posted November 27, 2023 The more I look at your log files, the more confused I am... Can you explain exactly what happens please, and what you do.... The WASM log file indicates that you went back to the main menu: Quote Mon Nov 27 13:27:05 2023 [INFO]: Flight loaded: 'flights\other\MainMenu.FLT' Mon Nov 27 13:27:05 2023 [DEBUG]: In main menu - de-activated and config data area cleared Mon Nov 27 13:27:05 2023 [TRACE]: EV_FLTLOADED done But there is no indication of this in your FSUIPC log file, it just loses the WASM config and is waiting for new data: Quote 196766 [TRACE]: Values received event completed 209297 [TRACE]: SIMCONNECT_RECV_ID_CLIENT_DATA received: Empty EVENT_CONFIG_RECEIVED - requesting again 209312 [TRACE]: Config data requested... 209312 [TRACE]: SIMCONNECT_RECV_ID_CLIENT_DATA received: Empty EVENT_CONFIG_RECEIVED - requesting again 209328 [TRACE]: Config data requested... [timestamp 209297 is approx 14:23:35 + 3m29s = 14:27:04, and the 1 hour difference is due to different time zones being used] Did you go back to the main menu, and if so when? Before or after FSUIPC stopped responding or was killed? It looks like it just stays like this until it is killed. Are you sure there is no response from the UI? What is the message in the FSUIPC7 main window when this happens? If you keep the logging console window open, is this still logging messages, and if not what is the last message logged? And the WASM log looks like it has been uploaded AFTER MSFS has exited. When your issue occurs again. can you attach all files before you do anything else, so I can see the contents when the issue occurred. You also have a lot of stuff running using simconnect connections: Quote > 52.14517 [320, 1]Open: Version=0x00000005 Name="fs2crew-data-proc" > 52.14709 [321, 1]Open: Version=0x00000005 Name="fsdt-msfs-bridge" > 52.15186 [322, 1]Open: Version=0x00000005 Name="FSUIPC.LVAR.WASM" > 52.15323 [323, 1]Open: Version=0x00000005 Name="noolaero-vdgs-cyul" > 52.15589 [324, 1]Open: Version=0x00000005 Name="noolaero-vdgs-lirf" > 52.16012 [325, 1]Open: Version=0x00000005 Name="MobiFlightWasmModule" > 52.20987 [326, 0]Open: Version=0x00000004 Name="FenixBootstrapper" > 52.24447 [327, 1]Open: Version=0x00000005 Name="Couatl" > 52.24586 [328, 1]Open: Version=0x00000005 Name="FSHud" > 52.24926 [329, 1]Open: Version=0x00000005 Name="Request Data" > 52.25470 [331, 1]Open: Version=0x00000005 Name="FS2Crew Command Center" > 52.25790 [332, 1]Open: Version=0x00000005 Name="FS2Crew - RAASPRO for MSFS" > 52.26360 [333, 1]Open: Version=0x00000005 Name="FSUIPC7" > 52.26700 [334, 1]Open: Version=0x00000005 Name="FSUIPC7_AItraffic" > 52.26877 [335, 0]Open: Version=0x00000004 Name="FenixBootstrapper" > 52.27133 [336, 0]Open: Version=0x00000004 Name="FenixBootstrapper" > 52.27438 [337, 0]Open: Version=0x00000004 Name="FenixBootstrapper" > 52.28036 [338, 1]Open: Version=0x00000005 Name="PilotsDeck" > 52.28088 [339, 0]Open: Version=0x00000004 Name="FenixBootstrapper" > 52.28565 [340, 0]Open: Version=0x00000004 Name="FenixBootstrapper" > 54.53205 [341, 1]Open: Version=0x00000005 Name="WASMClient" > 63.67479 [342, 1]Open: Version=0x00000005 Name="DynamicLOD" > 63.71766 [343, 1]Open: Version=0x00000005 Name="FenixQuartz" > 63.82159 [344, 1]Open: Version=0x00000005 Name="Fenix2GSX" > 139.24870 [345, 1]Open: Version=0x00000005 Name="FSUIPC-WASM-IF" > 209.93584 [346, 1]Open: Version=0x00000005 Name="Couatl" > 210.61520 [347, 1]Open: Version=0x00000005 Name="DynamicLOD" > 211.15578 [348, 1]Open: Version=0x00000005 Name="WASMClient" Not sure why you are running so much Fenix stuff when you are not even using that aircraft - have you considered moving this out of your Community folder if not being used, and not running any additional software for that aircraft if not being used? Easy to do with the MSFS Add-on manager. Note sure why you are using/running the WASMClient either - twice! You really don't need this - everything that does can be done in FSUIPC.

Flying the Fenix represents the most-demanding Workload, and the Sim and my PC don't have a Problem with that. My Fenix Tools are only two: Fenix2GSX and FenixQuartz. They don't do anything actively after Connection until the Fenix Binaries are actually loaded. The FenixBootstrapper comes from the Fenix it self.

I have two Tools opening an FSUIPC / WASM Connection through the C# Client (PilotsDeck and WorkingTitle2GSX) - maybe that's why? What these Programs do can not be done in FSUIPC. I can't tell you why GSX/Couatl is listed twice there. Maybe that is just part of the normal Behavior. As far as I can tell it restarts itself when returning to the Main Menu.
