Random Ubuntu system crash with Discord

[ghost]

Hi everyone,
I have daily crashes on my machine apparently caused by Discord, here are the logs attached. At 11:40, I get a full crash then a restart of my machine with a purple screen (but no login window). I would be grateful to anyone that could point me in the right direction. Thanks a lot.

Also experiencing this -- every few minutes Ubuntu will freeze for a good 20-30 seconds and the culprit appears to be Discord. syslog is getting spammed with:
kernel: [574301.017397] audit: type=1400 audit(1525965944.924:13917858): apparmor="DENIED" operation="ptrace" profile="snap.discord.discord" pid=7295 comm="Discord" requested_mask="trace" denied_mask="trace" peer="unconfined"

Does this stop if you issue snap connect discord:process-control

[MGD1981]

Trying that gave me: kernel: [575439.871705] audit: type=1400 audit(1525967083.778:13936376): apparmor="STATUS" operation="profile_replace" profile="unconfined" name="snap.discord.discord" pid=8614 comm="apparmor_parser"

Per someone else's post I already tried snap connect discord:system-observe, which seems to have changed the continual errors from operation="ptrace" to operation="capable", and the logs are much less frequent now, but I'm still getting the frequent freezing behavior.

Same problem on Ubuntu 18.10.
So, do we have solutuions ?

[magarto]

I have exactly the same problem in Ubuntu 18.04
Some random crashes but, when opening a voice chat it always make the system crash in some minutes.

Same problem in linuxmint 19.1 cinnamon. After playing a game if you try to close discord ,it freezes the entire system for good 2 minutes. have to either wait 2 min or force close discord. Anyone got a soln ??

I'm having the same issue and I have the same log entries before my crash as well.

kernel: [ 507.886027] audit: type=1400 audit(1558630420.855:9528): apparmor="DENIED" operation="ptrace" profile="snap.discord.discord" pid=3838 comm="Discord" requested_mask="read" denied_mask="read" peer="unconfined"

is this still an issue?

[KevinBaudin]

Experiencing the same here on 20.04

[Fuseteam]

odd i don't have it on 18.04

I think you need to look elsewhere for your crash issue (maybe it doesn't print anything to syslog?). The apparmor denied messages are normal and while they're very spammy in the log it hasn't caused any issues for me.

For people on Ubuntu, I had some issues. It was crashing every time I was streaming. One Day, a friend told me it was based on Chrome. So I install chromium drivers it works for me.
sudo apt-get update -y
sudo apt-get install -y chromium-chromedriver
After installing this restart Discord.
I hope this resolves your problem.

.......wut? does this mean it's an electron issue?

[a1eaiactaest]

I think it's stiil a thing right now

[Fuseteam]

i still don't experience this with snap on ubuntu 18.04

[a1eaiactaest]

Does this stop if you issue snap connect discord:process-control

I did this and I think it worked, I'll see later today.

I had the same issue on Ubuntu 20.04.1. It seems that this solution fixed it: I don't get the annoying log messages anymore. Hopefully, the crashes will be gone as well.

Thanks for reporting everyone!!

This appears to be fixed now in the latest version of the snap, so I'm closing this issue now. Please comment if this is not the case.

Hey, it might be happening again, causing random restarts.
