[SOLVED] How do I get systemd to stop handling core dumps itself?

Based on advice in other threads, I did this:

# ln -s /dev/null /etc/sysctl.d/coredump.conf
# /lib/systemd/systemd-sysctl

but it didn't work; /proc/sys/kernel/core_pattern still contains "systemd-coredump ...".  Furthermore, the processes that I have dumping core do so when using a lot (many GB) of memory, so the core dumps are huge.  This causes systemd-journald to eat up 100% CPU for a long time after core dumps.

Also, how do I delete the ones that are already saved (that show up in systemd-coredumpctl)?

Hello tavianator.

This didn't work for me either, so i changed the link to:

# ln -s /dev/null /etc/sysctl.d/50-coredump.conf

After that /proc/sys/kernel/core_pattern shows "core" only.

Hope that helps.

Edit: I used the naming convention from /lib/sysctl.d/ which is also "50-coredump.conf".

@steinchen: I can confirm that this works for me, too. What a relief, thanks!

Hi, in case this isn’t working anymore (as some people say), you may refer to the updated instructions on the wiki to restore normal core dump files that work for me!
