SYSTEMD-COREDUMP(8)                      systemd-coredump                     SYSTEMD-COREDUMP(8)



NAME
       systemd-coredump - Log and store core dumps

SYNOPSIS
       /usr/lib/systemd/systemd-coredump

DESCRIPTION
       systemd-coredump can be used as a helper binary by the kernel when a user space program
       receives a fatal signal and dumps core. For it to be used in this capacity, it must be
       specified by the kernel.core_pattern sysctl(8) setting. Systemd installs
       /usr/lib/sysctl.d/50-coredump.conf which configures kernel.core_pattern to invoke
       systemd-coredump. This file may be masked or overriden to use a different setting
       following normal sysctl.d(5) rules.

       The behaviour of a specific program upon reception of a signal is governed by a few
       factors which are described in detail in core(5). In particular, the coredump will only be
       processed when the related resource limits are high enough. For programs started by
       systemd those may be set using LimitCore= (see systemd.exec(5)).

       systemd-coredump will log the coredump including a backtrace if possible, and store the
       core (contents of process' memory contents) in an external file on disk in
       /var/lib/systemd/coredump, or directly in the journal. This behaviour may be modified
       using coredump.conf(5).

       Apart from the journalctl(1) log viewer, coredumpctl(1) may be used to list and extract
       coredumps.
