Are you sure there are no errors logged? The above messages could be in
a different log file than errors. See http://wiki.dovecot.org/Logging

If there really are no errors, it can only mean that the main dovecot
process crashed. Then it should have written a core file to base_dir
(/var/run/dovecot/). If not, run ulimit -c unlimited before starting
dovecot.
