v1.12.0 seems to be crashing all the time

[jrdoublet]

Hi, I run 2 firefox containers, one with v1.11.0 and one with v1.12.0 my docker compose files are exactly the same except the version

v1.12 crashes all the time v1.11 is fine

here's my docker compose file :

What do you mean exactly by "is crashing"? Firefox doesn't start ? Could you provide the container's log ?

[alexsahka]

My is crashed as well.

@alexsahka, you seem to have a different issue. Did you set the --shm-size parameter ? https://github.com/jlesage/docker-firefox#increasing-shared-memory-size

I am also seeing this in the latest, my tabs keep randomly crashing. I also already had the --shm-size 2g. I am running the Docker container on my unraid. v1.11 worked perfectly fine.

I'm sorry, I couldn't find the logs, could you please help me ?

I've retrieve these logs, but they're useless :

ok I think I found the logs

I've seen two errors :

• 1st one in nginx/error.log : Crash Annotation GraphicsCriticalError: |[C0][GFX1-]: Failed buffer for 0, 0, 1600, 885 (t=233447) [GFX1-]: Failed buffer for 0, 0, 1600, 885

• 2nd one in firefox/error.log :

I hope this helps

[jlesage]

The tab crash seems related to a system call not allowed by default by Docker. This particular system call (membarrier) will be whitelisted in the next Docker version.

For now, a quick workaround is to create the container with the following option:

--security-opt seccomp=unconfined

I will provide more details on the issue and the possible workarounds in the documentation.
