dovecot - Feb 2012 - Configuration problem?

I have a new Scientific Linux 6.1 mail server (dovecot -n below) and
am seeing the following in the logs, with no idea what is happening:

 --------------------- Dovecot Begin ------------------------


 Dovecot was killed, and not restarted afterwards.

 ---------------------- Dovecot End -------------------------

 dovecot -n
# 2.0.9: /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-131.0.15.el6.x86_64 x86_64 Scientific Linux release
6.1 (Carbon)
mail_location = maildir:~/Maildir/
mbox_write_locks = fcntl
passdb {
  driver = pam
}
protocols = imap
ssl_cert = </etc/pki/dovecot/certs/dovecot.pem
ssl_key = </etc/pki/dovecot/private/dovecot.pem
userdb {
  driver = passwd
}

/etc/dovecot/dovecot.conf: - everything being defaults, as far as I
can see, apart from these lines:

# Protocols we want to be serving.
protocols = imap
listen = *, ::
mail_location = maildir:~/Maildir/
maildir_copy_with_hardlinks = yes

Is it really expecting an mbox file?

I'm completely bogged down with this - my previous setup was fine, but
the old config file doesn't work with this system.  Any help and/or
pointers would be greatly appreciated.

You shut dovecot down and does not restart it.

The user closed the connection.

The server closed the connection due to a shutdown command.

Dovecot did what it just said: it started.

Your logwatch is to old to knew about the messages dovecot emits to
syslog.
