Random Game Crash

[o34n22]

Does anyone else encounter this problem? MP as well as SP games crash randomly. I inserted the head of debug.log

Can you post your exception.log as well, please?

I'm also getting this on Linux with playtest-20180102. I have no exception.log file in ~/.openra/Logs/
I get this stacktrace on the terminal:

What was your last action when as this happen?

Unfortunately this is not an OpenRA crash, so there may not be much that we can do to help.
What mono version and linux distro are you running?

[onnd]

I don't remember doing anything specific when it crashed, had been playing for about an hour.

I'm running gentoo with mono 4.4.1.0. Never got this with openra-20170421 which I was running previously, but I realise it can still be a bug in mono. I'll try with other newer versions of mono...

@o34n22 your crash has nothing to do with this ticket and I suspect it's caused by the custom LUA of the map you played on, asin https://resource.openra.net/maps/22557 .

[pchote]

@GraionDilach @o34n22 is the person who created this issue, so it has everything to do with this ticket!

[LipkeGu]

@pchote #14654 fixes this but every one says we cant skip orders :( The problem is that this crash is happen when:

get malformed Orders from clients (smaller than 4 bytes, maybe null or entire empty data).
var ms = new MemoryStream(bytes, 4, bytes.Length - 4);

https://github.com/LipkeGu/OpenRA/blob/b4d94300f5bb0fb6d5cfa1872f8dff81dbe512f8/OpenRA.Game/Network/OrderIO.cs#L26

I noticed while trying to join a local dev game a noticable "lagging"... but cant get it to crash it also seems that something not gets disposed, i tried to join my own server > 100 and VS shows increasing memory usage and it laggs on the "Joining" client. As i begun to reproduce it was 372 MB at the enhd it was 513 MB

[noobusinglinux]

yes im currently running Ubuntu 18.04.1 LTS. and im seeing the same error in the debug log after openRA crashes heres the logs
debug.log

install.log

perf.log
server.log

traitreport.log

[guushoekman]

I recently upgraded to Xubuntu 19.04 and this crash happened on both games I've played since doing the upgrade. Had it a handful of times in the six months I used 18.10. No exception.log file.

mono --version gives me

Not sure if that's relevant in any way.

[conkerts]

I'll join this thread.
Got several System.NullReferenceExceptions after playing in MP, on Kubuntu 19.04 for about 10 min.
I have the same mono version @guushoekman .

I can provide the logs, if needed.

[pchote]

Ubuntu 19.04 ships a buggy version of mono. Follow the instructions on https://www.mono-project.com/download/stable/#download-lin to update to a fixed version.
