Hi Jerry,
I had a similar crashes in imap-2007f running on SLES 11.3. I debugged
the source code; it turned out, there were two bugs. I fixed them and
that resolved the crashes for me. I sent my patch to this list, but I'm
not sure that anyone cares as UW IMAP doesn't seem to be maintained anymore.
Even though I was able to fix the problem, I lost confidence in UW imapd
and switched to dovecot. So far, dovecot has shown to be superior in
every meaningful way.
Regards
Erik
