It does check if a process is running with that PID. Doing any further checks to make sure that the PID is a dovecot process would probably be more trouble than worth.
Hmmm ... something strange must have happened, because it sure looks like to me that the test failed.
Dovecot reported that the old PID was 1965. Per my previous message, I did a 'ps 1965' and saw no processes:
[root@mykiss5 mth]# service dovecot start Starting Dovecot Imap: Error: Dovecot is already running with PID 1965 (read from /var/run/dovecot/master.pid) Fatal: Invalid configuration in /etc/dovecot.conf [FAILED] [root@mykiss5 mth]# ps 1965 PID TTY STAT TIME COMMAND [root@mykiss5 mth]# rm /var/run/dovecot/master.pid rm: remove regular file `/var/run/dovecot/master.pid'? y [root@mykiss5 mth]# service dovecot start Starting Dovecot Imap: [ OK ]
Once I manually removed /var/run/dovecot/master.pid it started up.
*** 5 minutes later ***
Well, I just tried to reproduce this by hand, but was not able to.
[root@mykiss5 mth]# cd /var/run/dovecot/
[root@mykiss5 dovecot]# ls
auth-worker.3053 dict-server login master.pid

I have no idea why it failed after the unclean shutdown/restart ... curiouser and curiouser.
