This isn't really enough to diagnose a problem. Can you try obtaining a backtrace?

[remco-pc]

@iluuu1994 that should be enough, because its a general protection fault and hangs the system probably, its probably a simple task manager script but if you can tell me the parameters i might for example log the pids and trace it back to the script,

You could create an id for it and keep the documentation for it somewhere, link to the problem and howto solve it, next time

i have this error executing this:

bash: /proc/sys/kernel/core_pattern: Read-only file system

echo "/core-%e.%p" > /proc/sys/kernel/core_pattern

probably due to the docker image, do i need to put it in the server debian version which hosts the docker container, and does it then still work ?

[iluuu1994]

core_pattern needs to be set in the Docker container. It won't help to set it on the host.

its on a production site and i dont want to set the priveleges to this level, i will try to use the php version with the debian image first, checks if it then not hangs anymore before i will put the priveleges on it.

@iluuu1994 is [1907] the pid ? i can log the pid processes then and check what script causes this, it might be a hacker

Any news, @remco-pc? As is, this ticket is not actionable.
