NAME

6       systemd-coredump - Log and store core dumps

SYNOPSIS

9       /usr/lib/systemd/systemd-coredump
10

DESCRIPTION

12       systemd-coredump can be used as a helper binary by the kernel when a
13       user space program receives a fatal signal and dumps core. For it to be
14       used in this capacity, it must be specified by the
15       kernel.core_pattern sysctl(8) setting. Systemd installs
16       /usr/lib/sysctl.d/50-coredump.conf which configures kernel.core_pattern
17       to invoke systemd-coredump. This file may be masked or overriden to use
18       a different setting following normal sysctl.d(5) rules.
19
20       The behaviour of a specific program upon reception of a signal is
21       governed by a few factors which are described in detail in core(5). In
22       particular, the coredump will only be processed when the related
23       resource limits are high enough. For programs started by systemd those
24       may be set using LimitCore= (see systemd.exec(5)).
25
26       systemd-coredump will log the coredump including a backtrace if
27       possible, and store the core (contents of process' memory contents) in
28       an external file on disk in /var/lib/systemd/coredump, or directly in
29       the journal. This behaviour may be modified using coredump.conf(5).
30
31       Apart from the journalctl(1) log viewer, coredumpctl(1) may be used to
32       list and extract coredumps.
