FSX CTD

[marks217]

Hello,

I unfortunately suffered an FSX CTD at 1,500 feet on my approach and I'd like to figure out what the issue was and if it was related to FSUIPC at all.

Everything was going normally until the simulator locked up around 1,500 feet, froze for a minute or two, and then closed. This was on VATSIM in a busy airspace, though my sim will usually just stutter in such instances without crashing.

The Windows crash details indicate FSRecorder as the faulting module, though it seems to always throw up the same .dll as the faulting module after a CTD. I was not using FSRecorder at the time, nor had I used it at all during this particular flight. Here's the report anyway:

Faulting application name: fsx.exe, version: 10.0.61637.0, time stamp: 0x46fadb14
Faulting module name: RecorderFSX.dll_unloaded, version: 1.3.0.0, time stamp: 0x4772d03d

Here's another one from less than a minute later. Looks almost identical.

Here's a final one from 13 minutes later, perhaps when I tried to relaunch FSX. This one lists ai_player.dll as the faulting module.

Faulting application name: fsx.exe, version: 10.0.61637.0, time stamp: 0x46fadb14

I've attached the FSUIPC4.log file to the post.

This is an unregistered copy of FSUIPC and I just updated it the other day through DVA ACARS. I was flying an addon 717 (can look up developer later if needed). Addons I was using were ASN, DVA ACARS, projectFly, vPilot, and Self Loading Cargo. I had also used FS Real Time early in the flight but was not at the time.

I know it doesn't look like FSUIPC was at fault, so I'm just trying to get to the bottom of what happened. Self Loading Cargo users have been reporting issues with a recent version of FSUIPC, but it may be for MSFS, I'm not sure, or if that's related to my issue. Any help would be appreciated. Thanks in advance.

Weather file corruptions are the most usual cause of weird crashes in different places.  Try setting NoWeatherAtAll=Yes in the [General] section of FSUIPC4.INI.  That stops it asking for weather data from SimConnect and so doesn't force SimConnect to read the bad data.

If that seems to fix it, remove that added parameter and instead find and delete your wxstationlist.bin file in your FSX AppData folder, and all of the saved .wx files in your FSX Documents folder. The bin file wil be regenerated next time you run FSX, and .wx files are created each time you save a flight.

If that doesn't help, then I'm sorry but I can't really help. I think yo will need to do a process of elimination. Start by removing that RecorderFSX.DLL. Although you weren't using it at the time those tow crashes in it certainly occurred when it was doing something.

Incidentally, the FSX log file you provided doesn't show anything -- FSUIPC closed down tidily when SimConnect called it to say FSX was closing (tidily). No crash.

Thanks for your response, Pete.

I will definitely try that weather parameter next time and I'll report back.

Just to better my own understanding, do you have any idea what that RecorderFSX.DLL could have been doing? My only guess is that it gets loaded when FSX starts up, but without actually using it, I'm not sure what could have forced it to go wrong. If not, no worries.

Looks like it 'adds improved recording and replay features to FS' , from here.

You can disable it by editing your dll.xml and changing the <Disabled> entry for that module to True.

Oh, I already know that. I've used it many times before. My apologies for the misunderstanding. I meant what it might have been doing at that specific time that may have caused a crash. To my understanding, it gets loaded with all of the other DLLs in the dll.xml upon starting FSX, but I hadn't used it at any point at all during the flight.

Hopefully this is just a corrupt weather file somewhere as Pete suggested. As soon as I get some free time to test that fix, I will let you know what happens.

Nevertheless, it is still code being executed, ready to obey your commands.

Well, it just crashed again at 14,000 feet on descent, so I guess that added flag didn't help. I'm happy to post any reports or logs, but I guess it's time to start narrowing things down. SLC is the newest addition to my previously stable setup, so I'm guessing that everything running is just using too much memory.
