}Verify ProcessSizeMax in /etc/systemd/coredump.conf
Description
The ProcessSizeMax setting sets the maximum size in bytes of a core which will
be processed. Core dumps exceeding this size may be stored, but the backtrace
will not be generated.
Setting Storage=none and ProcessSizeMax=0 disables all coredump handling
except for a log entry.
Rationale
Kernel core dumps may contain the full contents of system memory at the time of the crash. Kernel core dumps may consume a considerable amount of disk space and may result in denial of service by exhausting the available space on the target file system partition.
