Further to Graeme's suggestions:
- Is your Exim built with debug symbols? If not rebuild
it with debug symbols (gcc option -g), otherwise
debugging will be difficult.
- Is exim dumping a core file? If not, figure out why
not and fix it, so that you have something to examine.
- Are the fault addresses reported always the same?
- What does addr2line say about the instruction pointer
address at which the fault is reported?
- What was that exim process doing at the time it
crashed (if your logs don't tell you add more
logging)? Was it an SMTP listener, invoked by another
process, a delivery process, a queue-runner etc.?
- Against what external libraries has exim been linked?
(E.g. RDBMS client libraries.) Do you need all of
them? If not, rebuild it without the unnecessary ones
linked and see if the problem persists.
On the plus side if you're seeing crashes every twenty
minutes this shouldn't take long to diagnose. It's the
crashes that occur every twenty days that are a pain.
