AFAIR dovecot is using some linux-mechanism (epoll?), which is no part of freebsd.   Regards Hanns _______________________________________________ dovecot mailing list -- dovecot@dovecot.org To unsubscribe send an email to dovecot-leave@dovecot.org   Has nothing to do with epoll. Dovecot uses kqueue on FreeBSD. This indicates clock issues, you should use ntpd to avoid this, alternatively your VM/machine is lagging and clock is jumping forward.   Aki
