message in /var/log/maillog

directory
Jun  1 20:30:16 foo dovecot: Auth process died too early - shutting down

I've read the http://wiki.dovecot.org/CompilingSource but am stuck now
with this issue.
i also googled around a bit but could get any more information about
this problem.
any help is appreciated.

thanks in advance.
