dovecot - May 2003 - 0.99.9.1 - Runaway imap-login process

/etc/dovecot.conf:
auth_userdb = passwd
uth_passdb = pam

I think this was triggered while I attempted to login to IMAP with the
this dovecot configuration without adding an "imap" entry to
/etc/pam.d/
(auth fails).  When I attempt to strace -p this runaway process, it
strangely displays nothing.  kill was able to get rid of it.  After I
added an appropriate /etc/pam.d/imap entry, auth works and I didn't see
this runaway process.

This is a RH9 chroot server instance running within Linux virtual server
with security contexts kernel.  (Think of it as a theoretically
unbreakable chroot.)

Any tips on what I can do to get some debugging information out of this?

Thanks,

If strace didn't show anything, I guess it got stuck to infinite loop
somewhere.

gdb /usr/local/libexec/dovecot/imap-login 32116
bt

would show where it's stuck at.
