Dovecot error in configuration

[Juddling]

protocols = pop3
listen =
ssl_listen =

protocol imap {
}

protocol pop3 {
pop3_uidl_format = %08Xu%08Xv
}

protocol lda {
postmaster_address = postmaster@example.com
}

auth default {
mechanisms = plain

passdb pam {
}

userdb passwd {
}

user = root
}

dict {
}

plugin {
}





That's my dovecot conf and when i start dovecot:

[root@server40341 ~]# /etc/init.d/dovecot start
Starting Dovecot Imap: Error: Dovecot is already running with PID 1128 (read from /var/run/dovecot/master.pid)
Fatal: Invalid configuration in /etc/dovecot.conf


can anyone see the problem?
