FGU crashes using 5E ruleset

If it will actually help, I can make all of the logs available for download.

Crash from a week ago ... relevant info from the Player-prev.log

Please do include the full logs using the Compile Logs function. Details in the link in my signature.

As this is not happening (that I know) to others, there is something unique in your setup. Things like o/s, versions, extensions, rulesets and reproducible steps that cause the issue would help us help you identify the root cause and/or solution much quicker.

Seems that I'm one of the many waiting for Unity to become more stable. And, it seems that the issues are related to using drivers FGU installs ... .smiteworks/fantasygrounds/FantasyGrounds_Data/Mono/libKernel32 ... and using "too much" of the paid content (bought on FG's site) and/or FGU software at once ... like having 20 to 50 modules open where 20 are shared with players while trying to 20 to 30 windows open.

Another person who seems to have the same issues ... https://www.fantasygrounds.com/forums/showthread.php?57359-FGU-stability-issues/page5

If you want to know more about my setup and how I rule out "my setup" by testing fresh "setups" and reproduce ... https://www.fantasygrounds.com/forums/showthread.php?65632-FGU-crashes-using-SFRPG-ruleset&p=575423#post575423 ... but it is SFRPG.

I keep hearing from people who seem to be FG employees or insiders that they know this is an issue. I just keep hoping that we get some communication about it.

Do you really need so many modules? (not to say anything against performance improvements) Just use the modules you need for the preparation, and unload anything else :) You may even unload some modules which you do not need for the live game (which you just needed for the preparation)

EDIT: And as LordEntrails mentioned, it might still be useful to upload the full log :)

We need the full logs to do any checking; as this includes machine information as well as information about the error, things loaded, etc.

Hi,

I have the same issue on LMDE 4 (Cinnamon 4.8.6), 5e ruleset: FGU crashes once in an hour or so. Usually this occurs when something is happening on the map with LOS enabled.
I'm attaching logs, please let me know if you can somehow help with this issue, because it's quite upsetting having 3-4 crashes during the game session, it completely ruins the mood sometimes :)

UPD:
Actually, I just left FGU running and went AFK for about 2 hours, and it crashed by itself with no interaction on my side and without anyone touching the PC at all. I'll attach logs for that as well (*crash2)

Thanks.

Sounds like a Linux distro issue and I don't think that one is officially supported. But not knowledgeable enough to know.

Have you checked the Linux thread? Try seeing if it has any good info for you; https://www.fantasygrounds.com/forums/showthread.php?61261-Linux-Testing

Thanks for the link, I'll check it.

I'm continuing to get a crash while running Rime Frostmaiden. I didn't get server logs (which is Linux), but got a player to give me their logs (Windows 10), so posting here. Doesn't seem to be OS related as I've had it occur with server running in both Windows 10 and Linux.

Had a custom map open this time with no LOS, but did have Blizzard effect on. Occurred 2 hours 40 minutes into session. I was dragging a saving throw from NPC sheet and about to drop on PC token.

All I can see in the logs right now is a timeout disconnect on the player side.

* Can you clarify what you mean by "crash"?
* Is the client crashing to desktop (completely unloaded), throwing errors, or returning to launcher? Or something else?
* Did the GM client have problems first which killed the player connection; or did the player client have the problem?

If it's the GM machine, we need the GM logs, as the player logs won't have any details other than the fact the the GM client timed out.

CTD, or crash to desktop. My server side just quits completely. Players get punted back to login. I posted server side logs a few weeks ago in the Linux thread. I didn't get server side logs this time.

[Moon Wizard]

Yeah, in those cases, player logs will not help. Most of the logs we've received for Linux crashes after a few hours were out of memory situations. We've been slowly plugging memory leaks as we find them; so this should get better over time.

Started using the Test Channel version last night to see if there's any improvement. I'm happy to report that using the 5E ruleset with many paid modules (> 10) open and shared, we had a "crash free" session. Also, we all noticed less "lagginess" as compared to the Live Channel version.

If clean logs have any use, let me know, and I'll upload them.

I will update the "FGU crashes using SFRPG ruleset" thread on Sunday: https://www.fantasygrounds.com/forums/showthread.php?65632-FGU-crashes-using-SFRPG-ruleset.

Follow up post to share good news ... After about 2 years, FGU on Linux has finally become as stable FC 5E.

FGU: v4.1.4 ULTIMATE (2021-06-08)
OS: Linux 5.12 Fedora 34 64bit

The campaign was up and active for about 4 hours with no issues, and, as a test, I left the campaign up over night for another 10 hours, and no crash. Things are finally looking up for us and FGU. We are still having lag issues, but I'm starting to think that 8 to 10 players might be outside of FGU's sweet spot for avoiding lag. We are using LOS and Lighting. Since stability issues seem to be behind us, I'm going to start another thread regarding my investigations into the lag.
