Description Giovanni Campagna 2013-01-20 15:09:06 UTC 
In all coredumps collected by systemd-coredump and retrieved with coredumpctl, I fail to run gdb with:

BFD: Warning: /home/giovanni/core is truncated: expected core file size >= 449388544, found: 25165824.

And the resulting coredump is completely unusable (not even a backtrace or the failure signal).

Looking at coredump.c, I see a maximum limit of 24M, which is not enough. This limit should increased, or at least made configurable.
Comment 1 Zbigniew Jedrzejewski-Szmek 2013-07-16 02:46:09 UTC 
The limits is now 768*1024*1024 bytes which should be enough for most cases. This is also what systemd-journald allows [1].
