>Description:
Server is using MPD authorization, ipnat address translation; serves proxy, sendmail, popa3d, BIND and MySQL daemons.
Problem begin to appear in 6.1-RELEASE with same error and after CVSup to 6.2-PRERELEASE on Feb, 6 problem doesn't solved.
Server is running on single core AMD Athlon 3500+, have two Intel Gigabit NIC's (em) and one Intel 100Mbit NIC (fxp).
Below I paste core debug information.
