I administer a box running v4.2-stable with a pair of the Adaptec ANA-62044 64-bit PCI, Quad port ethernet adapters. Six of the eight ethernet ports are in use. The box routes traffic between five private networks and provides NAT services out the public world on the sixth interface. I encounter an intermittant problem where one of the ports on a private network will quit functioning (usually sf2 or sf3). Nothing on that segment can reach the machine and if I try to ping something on that segment from the box in question I get: ping: sendto: No buffer space available The other five ports in use on the system continue to function normally. If I "ifconfig sfX down/up" the problem goes away. I've seen the problem as often as twice a day and sometimes gone a month without seeing it. The private segments carry very heavy SMB traffic. I have upped NMBCLUSTERS to 8192 with no success. Influenced by what I found digging though the DejaNews archives, I have also increased maxusers from 32 to 128, but do not believe the box has been up long enough to see if this has made a difference or not. Since these settings are global to the OS and I'm only encountering a problem with one port at a time, while the others continue to function normally, I have doubts they are an issue and suspect is must be a problem with the sf driver itself. I have swapped-out the NICs, the PC, and encountered the same problem with v3.x-stable. Thanks for any help you might offer. Below I'll paste some pertinate system configuration info. -G /* Glen R.
