Hi All,
I am running OpenBSD 5.8, and tried 5.9 as well, on a SuperMicro PDSMi which
has an Intel 82573E.
For some reason networking just stops working after a random amount of time and
usually happens when I SSH-ed into the machine.
When connected to the console it seems to be working longer. I am testing this
by pinging an IP address on the local subnet.
Unfortunately I can not find anything different from an interface perspective,
subnet perspective and nothing appears in the logs.
The problem goes away, temporarily, when I bounce the interface on the switch.
How can I best troubleshoot the cause?
