imap failing

[@lbutlr]

mail kernel: pid 59433 (imap-login), uid 0: exited on signal 11 (core dumped)
master: Error: service(imap-login): command startup failed, throttling for 16 secs
May 15 17:21:37 imap-login: Fatal: master: service(imap-login): child 92934 killed with signal 11 (core dumped)

I also get a password error for a user unknown, but if I connect to the database with the credentials dovecot uses, I get a password.


MariaDB [postfix]> select password FROM mailbox where username ='sample at domain.munged';

I updated my system to openssl111 and rebuilt dovecot and postfix (and a hundred other packages). <y configuration files have not changed.

I've looked through he logs for other info, but I don't see anything. Trying to connect via openssl gives me:

# openssl s_client -connect mail.covisp.net:993 -starttls imap
CONNECTED(00000003)
