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: 1) strace -tt -p <pid> output for a 10 lines or so. 2) dovecot --build-options output
