Our server now running with
FreeBSD seth.uct.kiev.ua 4.5-RELEASE-p6 FreeBSD 4.5-RELEASE-p6 #0:
server acts as gateway for ~200 hosts/ips.
The system halts every 2-3 days, without any error reports!
We have following active ethernet interfaces on board:
xl0-3: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=3<rxcsum,txcsum>
media: Ethernet autoselect (100baseTX <full-duplex>)
status: active
Early, when we just set up new 4.1 we had problems with "out of
mbufs space", but after increasing NMNCLUSTERS problem gone.
But after CVSUP-ing to 4.5 we now stuck with this unpredicted crashes.
I read some topics on deja and saw that some other people
had same problems. But there was no answer/solutions.

Is this a "normal" behavior?
