I have experienced this a couple times since I installed 2.52-1 on a
Redhat 6.1 Linux box. I got a core dump once in the mqueue.in directory,
and it looks like it was a malloc problem that caused it, but I didn't go
into any detailed analysis. I just scheduled check_mailscanner to run
every 15 minutes via cron.
It is repeatable behavior, but I can't pinpoint when/where it is
happening. I don't really want to point the finger at mailscanner, as this
box is old, but pretty stable. It handles quite a bit of mail:
