I have a mail server running qmail and vpopmail, and FreeBSD 4.2. The machine does decent volume. Periodically the machine will just go deaf to network connections for 15 - 20 minutes at a time. When this happens, both the link light on the machine and the link light on the switch go amber. I've tried to troubleshoot this from every angle. I've checked the settings on the switch (they're fine). In fact, when this problem happens, the switch isn't reporting any errors on the port. I've swapped ethernet cables, put the machine on another switch, and swapped ethernet cards, all to no avail. There are no error entries in any of my log files that I can see. It seems like a hardware issue to me, but the problem occurs with both of the machine's ethernet cards, which are in different PCI slots. It also doesn't look like any sort of flood attack, as far as I can tell. I'm totally stumped. Is there anything in FreeBSD that I should be checking? Thanks
