With the launch of systemd, there's another scenario aswell. By default systemd will store core dumps in its journal,
|
|
being accessible with the coredumpctl command. Defined in the core_pattern-file:
|
|
|
|
$ cat /proc/sys/kernel/core_pattern
|
|
|/usr/lib/systemd/systemd-coredump %p %u %g %s %t %e
|
|
|
|
This behaviour can be disabled with a simple "hack":
|
|
|
|
$ ln -s /dev/null /etc/sysctl.d/50-coredump.conf
|
|
$ sysctl -w kernel.core_pattern=core # or just reboot
|
|
|
|
As always, the size of core dumps has to be equal or higher than the size of the core that is being dumped, as done by for example ulimit -c unlimited.
|
|
|
|
man systemd-coredump

|
