FSUIPC Crash?

[skelsey]

Hello,

 

Just had FSX crash on me -- on investigating with Event Viewer I was interested to note that FSUIPC was the faulting module.

 

Obviously it may well be 'one of those things' that never crops up again, but would be interested to hear any thoughts.

Any ideas? I did initially think it could be connected to the access violation referred to in the FAQ at http://forum.simflight.com/topic/73518-possible-solution-for-fsuipc-access-violation/- but closer investigation of the registry reveals that that particular key is not in existence, so therefore it must be something else.

 

Many thanks,

The data you've posted would be useful if it related to the currently supported version, 4.95. Please update and try again. Also, next time, please show me the FSUIPC4.LOG file, as far as it gets. That could also provide a vital clue.

 

From the offset the most likely area of FSUIPC is the Lua interpreter, so details of any Lua plug-ins you have running may be relevant too, as well as a description of what might have been going on at the time.

Ah -- I shall do! Thanks Pete. I'd only updated in the last couple of weeks so it didn't occur to me there might be a new version!

 

Interesting that it could be connected to the LUA interpreter.

LUA plugins -- just DynamicFriction and a couple related to the Aerosoft Airbus. AirbusX_Thr1 & AirbusX_Thr2 (which enable control of the Airbus thrust levers via FSUIPC) and Transponder_ab (which sends the SB offset from the transponder switch). There is also an A2A transponder LUA but I presume that wouldn't have been loaded.

 

As to what was happening -- not very much! It was an Aerosoft connected flight deck flight, so don't know whether that could have had any bearing on it, but other than that wholly unremarkable: we'd been flying for almost an hour and were just in the cruise (FL280, just south of the Scottish border). Just about to start descent, but I don't think that had actually been initiated when the crash occurred.

 

Hope that's useful -- however, I will go and update forthwith!

 

Best,

 

Simon

Interesting that it could be connected to the LUA interpreter.

 

Actually, looking at the Log that's not so likely. This line, being the last logged, is a very clear indicator:

 

351016 Advanced Weather Interface Enabled

 

Not sure why it took nearly 6 minutes for FS to get to this stage. Was it sitting at the selection screen a while?

 

Anyway, the fact that the crash occurred immediately after FSUIPC started reading the weather from SimConnect points to a corrupted file -- either the .WX file being loaded, or the wxstationlist.bin file in the folder where your main FSX.CFG file resides.

 

These files are just binary data, with no checks included, and if the get corrupted -- perhaps from a previous crash, or partial update from a weather supplier, then when SimConnect interprets them in order to provide FSUIPC with the extended METAR strings being requested, it cause a crash -- sometimes in WEATHER.DLL, sometimes in it's callback in FSUIPC, sometimes actually in simconnect itself, though that's pretty unusua because that DLL is really just a sort of "stub" passing things on to the relevant part of FS.

 

Try deleting, or moving out, the .WX files from your FS files folder in your Documents, and just deleting the wxstationlist.bin file. As you are using ASN you don't need the .wx files, and the .bin file will be regenerated in any case.
