Dear All, I have a FreeBSD box running 5.4-RELEASE-p8. Two interfaces: fxp0 - internet, SKA4 internal interface fxp0: <Intel 82559 Pro/100 Ethernet>
bge0 - internal with 30 vlans on it, old bge Gigabit 64/32 PCI-2.1 adapter. bge0: <Altima AC1002 Gigabit Ethernet, ASIC rev. 0x105> Firewall is pf with about 5000 rules.A week ago it was working just properly, but after adding more RAM (2GB additional RAM, and i do not thing that this is the reason of the problem) it starts to drop large packets. And the larger packet is - the more packets being droped, some of the does not appears to be incoming on bge interface, some of them being lost in between bge0 and fxp0 and some of them passing through. On the test with 1500 byte packets it looses about 40% (with 1400 it is 36%, with 512 byte packets it is 19%, with 256 byte packets it is 0). And strange thing. When i'm pinging with large packets from external host (at the same IP network and connected to the same switch) - it looses packets exactly the same way, but when i'm pinging from this host itself the others - no looses appears at all. So, looks like the interface sending packets just properly, but having trouble receivivng packets.
System load is almost 0% (1-5% in long term), sometimes 50% (sort term load, like mail antispam filter or antivirus). But it is 4CPU Pentium-III XEON, this should not be a problem and it was not a problem.
Does someone have any ideas? Best regards, Anton Nikiforov
