Customer has a FreeBSD 3.3-RELEASE machine (in a remote location, so a upgrade to 4.x is not so easily done) which suddenly decided it does not want to pass all network traffic. Here's the network card it has: tx0: <SMC 83c170> rev 0x06 int a irq 11 on pci0.10.0 tx0: address 00:e0:29:25:5f:1a, type SMC9432TX, Auto-Neg 10Mbps Pinging a host on the local network produces something like this: 64 bytes from 192.168.0.10: icmp_seq=6 ttl=128 time=1.702 ms 64 bytes from 192.168.0.10: icmp_seq=7 ttl=128 time=0.584 ms 64 bytes from 192.168.0.10: icmp_seq=8 ttl=128 time=4.104 ms 64 bytes from 192.168.0.10: icmp_seq=9 ttl=128 time=1.143 ms ping: sendto: No buffer space available 64 bytes from 192.168.0.10: icmp_seq=101 ttl=128 time=5.948 ms 64 bytes from 192.168.0.10: icmp_seq=102 ttl=128 time=31.502 ms ping: sendto: No buffer space available 64 bytes from 192.168.0.10: icmp_seq=104 ttl=128 time=0.638 ms So every couple of packets, it decides that it does not have enough network buffers available. Why? This was working just fine and absolutely no changes have been made to the machine since it was originally installed. Also network traffic on the LAN is not high at all. I have decided to recompile a kernel and increased maxusers to 128 and set NMBCLUSTERS to 4096. Nothing changed. I'm totally at loss as to what might be causing this. Ideas on how to solve this problem will be much appreciated.
