[Dovecot] service(imap-login): chiled ... killed with signal 11
Hi,
dovecot 2.0.3 After closing the imap(s) connection dovecot crashes:
imap-login: Info: Aborted login (no auth attempts): rip=... lip=... mpid=0 master: Error: service(imap-login): child 18636 killed with signal 11 (core not dumped - set service imap-login { drop_priv_before_exec=yes }) master: Warning: Killed with signal 15 (by pid=18643 uid=0 code=kill)
It also happens if I only telnet to the imap(s) port and give the only command "1 logout".
How can I get a dump for backtracing? With drop_priv_before_exec=yes I get a config error: doveconf: Fatal: Error in configuration file /usr/dovecot/etc/dovecot/dovecot.conf: service(imap-login): drop_priv_before_exec=yes can't be used with chroot
As user I can login and work normaly but I have to reconnect after a differnet connection will be closed causing a dovecot crash.
Additional information: Solaris 10, packages openssl, openldap by opencsw
I had seen a similar error during login process already with an rc-version. Because opencsw offers only an older version of openssl I installed current versions of openssl and openldap, So it works again. Now both packaged are up to date at opencsw. So I would like using these packages again when I install dovecot. Any hints?

Then it should be easy:
- telnet localhost 143
- gdb .../dovecot/imap-login <pid of imap-login process> cont
- logout to make it crash
- gdb: bt full

You need to also set inside the service "chroot=" to disable chrooting. Also for imap-login to produce core files you need to set "executable = imap-login -D".
