Extra information:
Everything goes well at the beginning. After a power failure, dovecot
doesn't work as well as it did. I attached the log at that moment to see if
it helps troubleshooting.

The config process is stuck for some reason. Try to find out what it's
doing. Immediately after you start dovecot, find the config process pid,
and do:
1) strace -tt -p pid (for about a second or so)
2) gdb -p pid
bt full
and mail the results.
