Thanks Randolph! That's interesting to know! What was the hardware you
were using? Does your bcast fail at the exact same point too?

How can I test for a buffer overrun?
For network saturation I guess I could use something like mrtg to
monitor the bandwidth used. On the other hand, all 32 servers are
connected to a single dedicated Nexus5000. The back-plane carries no
other traffic. Hence I am skeptical that just 41943040 saturated what
Cisco rates as a 10GigE fabric. But I might be wrong.
