NAME
       systemd-coredump - Log and store core dumps


SYNOPSIS
       /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 overridden to use a
       different setting following normal sysctl.d(5) rules.

       The behavior 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 behavior may be modified using coredump.conf(5).

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