Right.
Hmm.. I wonder if it might be due to the Solaris SMF system seeing the
coredump (and/or signals) and deciding that the system
it is monitoring has failed and thus shuts it down. (I use SMF to handle
Dovecot).
Ah! Yes, that's why!

Hmm...
Ah! The Solaris SMF FAQ 4.5 has a good answer on how to fix that.
Add the following to the Solaris SMF manifest that controls Dovecot:
<property_group name='startd' type='framework'>
<propval name='ignore_error' type='astring'
value='core,signal' />
</property_group>
Please find enclosed an updated Solaris SMF manifest that others might
be interested in using on Solaris 10/OpenSolaris systems...
