From first start after new installation (1.2.2) MBUF numbers are rising and
they newer go down.This is a busy firewall at university.
states are not so high 2228/100000 average is 3500/100000MBUF Usage 56314 /62340
Is this OK? Would I have same problem like with prior 1.2 install when system restarts after hitting the ceiling?

You might add more ram to the machine if you are really worried about it.
Do you use intel nic's?

There is only one different thing - this server have a bridge between WAN card and DMZ on VLAN. Normally for DMZ I have separate card.
I don't think that RAM is problem - there is 2 GB inside.
