Maybe you have run into the epoll kernel bug under RHEL/CentOS: http://dovecot.org/oldnews.html Thu Mar 22 14:38:53 EET 2012 Red Hat/CentOS users: A recent kernel update causes Dovecot to start failing after it has reached 1000 child processes. To fix this, downgrade your kernel until Red Hat releases a fixed kernel. See also: https://bugzilla.redhat.com/show_bug.cgi?id=681578 You should try another kernel: https://rhn.redhat.com/errata/RHSA-2012-1129.html Regards Daniel -- https://plus.google.com/103021802792276734820
