My dovecot logs revealed a crash in the dovecot/imap process a few
days ago. It appears to have dereferenced 0x00000004 in the storage
shared lib. Unfortunately, I didn't get a core and I'm not sure how
to reproduce it. Dovecot 2.0.8 on linux32.
1) How can I be sure I get a core next time? I think it's because I
run dovecot/imap under a mail uid and didn't have write permission
to the cwd. Any way to verify that was it, and be sure it works?
2) What other settings would provide more info if it happens again?
