Ubuntu 12.04.4 LTS, 64-bit
postgrey 1.34-1

postgrey regulary starts to reject all email with action "greylisted". I checked log files and I see these strange messages there:

Mar 6 02:11:39 mda postgrey[1086]: cleaning up old logs...
Mar 6 02:11:40 mda postgrey[1086]: cleaning up old entries...

Mar 6 03:11:39 mda postgrey[1086]: WARNING: can't checkpoint !? PANIC: fatal region error detected; run recovery at /usr/sbin/postgrey line 237.#012

This is critical bug from my point of view, it is kind of DOS attack because once this problem is triggered, all emails are rejected.
