[Dovecot] Dovecot crash in 1.0.9

[Peter Eriksson]

I've been having a problem with a crashing Dovecot the last couple of
months where it
crashes after a couple of weeks of uptime. Been a bit difficult to
diagnose. Anyway,
we're now running 1.0.9 on a Sun Fire T1000 running Solaris 10.

Any good ideas on how to pin-point the problem?
