/etc/init.d/dovecot start
Starting Dovecot Imap: Error: Dovecot is already running with PID 2145 (read from /var/run/dovecot/master.pid)
Fatal: Invalid configuration in /etc/dovecot.conf
시스템을 새로 부팅했더니 pid 가 없는데도 계속 오류가 나온다.
결론 : /var/run/dovecot/master.pid 를 지우고 새로 가동하라..

It doesn't seem to be that the current logic is working; there is no program with the PID that's in master.pid, and dovecot (1.0.7 + RHEL patches) refuses to start.

SELinux perhaps? It checks this by kill()ing the process and seeing if it returns ESRCH. If not, it assumes the process exists. If you've SELinux perhaps it always return EPERM to the call..
'getenforce' says disabled, so no. This is pretty strange -- I looked at the code and basically duplicated the logic there and could not reproduce this problem with a smaller piece of code. And it doesn't seem to appear always in any case -- I killed dovecot with KILL signal (leaving the PID file behind), and after that it started up without problems. Unless you have other ideas what to look for, I guess this will remain a mystery..
