Could you also do:

fr 5
p *index
p *map

Either timed out for some reason or some other strange bug..

With Linux this would be enough:

login_executable = .../imap-login -D

With Solaris you'll also have to somehow make setuid binaries dump core.
http://publib.boulder.ibm.com/httpserv/ihsdiag/coredumps.html says you
could do:

coreadm -e global-setid -e proc-setid -e global

Perhaps with those global core dumps it wouldn't even be necessary to
add the -D parameter. Anyway the -D's point was to make
the /var/run/dovecot/login/ directory writable to it, so it could write
core dump there.

I'm not really sure anymore if that even works (anymore). :)
