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.
