NIC Stops Passing Traffic
I am running a couple of Supermicro Servers with Atom Processors one is a D510 2 GB RAM (i386 builds) the other is a D525 4GB RAM (amd64 builds) Both have dual onboard Intel Gigabit NICs using the EM driver. This issue has been ongoing since the builds around mid January. I initially thought it was related to the kernel panics, but now i do not think so. They have been running in my lab for a few weeks now and were in production for several months until I updated one in mid Jan. Both boxes will boot and run fine for about 20 minutes then stop passing any traffic. The console is fine and I can typically make an initial connection to the web configurator, but then no more traffic will pass across the NIC.
The internet connection is a static T1 and I cannot ping from the console once it happens.
The issue continues as of the Feb 16 build. Is it the EM driver?

Please have a look at:
I had a similar problem on the same MB. Hopefully this will assist you getting your traffic flowing…
Here you go. The ping had been running about 30 seconds when the picture was taken.
Looks like the mbuf clusters. What does that mean? The system is currently connected to a 10/100 unmanaged switch (did it on a gig switch also) with 2 VoIP phones and 1 laptop.
