systemd-coredump failes due to timeout / System Administr...
LabRicecat · 2026-06-28 · via Arch Linux Forums

Hello, I have been experiencing severe and irregular lag spikes when booting up my PC. CPU nor GPU nor RAM do go up higher than usual, same for disk-usage. After finally looking around, I think I found the culprit.

Checking

I discovered that the systemd-coredump timed out after 5 minutes:

Jun 28 07:29:00 meow systemd[1]: systemd-coredump@0-1-2381_8463-0.service: Failed with result 'timeout'.
░░ Subject: Unit failed
░░ Defined-By: systemd
░░ Support: https://lists.freedesktop.org/mailman/listinfo/systemd-devel
░░ 
░░ The unit systemd-coredump@0-1-2381_8463-0.service has entered the 'failed' state with result 'timeout'.
Jun 28 07:29:00 meow systemd[1]: systemd-coredump@0-1-2381_8463-0.service: Consumed 3.853s CPU time over 5min 6.794s wall clock time, 5.5G memory peak.
░░ Subject: Resources consumed by unit runtime
░░ Defined-By: systemd
░░ Support: https://lists.freedesktop.org/mailman/listinfo/systemd-devel
░░ 
░░ The unit systemd-coredump@0-1-2381_8463-0.service completed and consumed the indicated resources.

I could confirm it failing by checking

  UNIT                                     LOAD   ACTIVE SUB    DESCRIPTION                       
● systemd-coredump@0-1-2381_8463-0.service loaded failed failed Process Core Dump (PID 2381/UID 0)

Legend: LOAD   → Reflects whether the unit definition was properly loaded.
        ACTIVE → The high-level unit activation state, i.e. generalization of SUB.
        SUB    → The low-level unit activation state, values depend on unit type.

1 loaded units listed.

This issue persisted even after updating my system fully. I sadly could not find any issues online that seemed related to this, anyone has a clue what might have gone wrong?
I saved the full journalctl -xe and dmesg of this right away.

Thanks a lot!
