Dear All,
I constantly encounter 'dovecot-auth', 'login-imap', 'login-pop3' and 'imap' processes consume 100% CPU. I run 'ps' and found those hanged up processes were running for a long time. I am wondering whether dovecot.conf has some configuration parameters that timeout those processes (or kill those after certain period of time). I am using dovecot 1.2.11 on RHEL 5.3.
There is no timeout value, because those processes just shouldn't be eating 100% CPU. Strange that all of your processes are eating 100% CPU. You do mean all dovecot processes eat 100% CPU, right? And it happens immediately after they start up? I guess there's something really wrong in your installation. A few things that might show something useful:
strace -tt -p <pid> output for a 10 lines or so.
dovecot --build-options output
