FreeBSD 4.9-p4

Od rana moj serwer poczty zaczal dziwnie "haczyc".
Wydaje sie za ma klopoty z tcp - ale nie moge zdiagnozowac w czym 
dokladnie problem - w logach nie ma nic specjalnego.

Objawy :
przy ping'ach gubi co 6,7 pakiet.
czasami zrywa sesje smtp i pop3 i generalnie "muli" sie przy 
wysylaniu/odbieraniu poczty.
