I would merrily gdb into a coredump and stacktrace away, if a core dump were 
created.  No such luck.

I'm now logging directly to file using syslog, after having started dovecot. 
  There is no limit on coredumps:

% limit
cputime         unlimited
filesize        unlimited
datasize        unlimited
stacksize       8MB
coredumpsize    unlimited
descriptors     64
vmemorysize     unlimited

dovecot: Jul 13 15:28:21 Error: child 14882 (imap) killed with signal 10

Environmental details:

	Solaris 7 (sparc)
	dovecot 1.0-stable
	compiled with ldap support
	using gcc 3.3.4
		  4.0.0
		  4.0.1  (no difference here)
	configured for mbox support
	with locking matching procmail's delivery locking strategies
	with authentication using passwd/shadow native databases


A header dump shows nothing suspect:

% elfdump -d /phil/sunos/sparc/pkg/dovecot-1.0-stable/libexec/dovecot/imap
