[c-nsp] Stability of NX-OS with FCoE/10GB

[Deny IP Any Any]

I have a pair of 5596UPs with 6 2K FEXes; I'm doing converged 10GB/FCoE to
a dozen big Dell VMWare boxes, and native FC to a SAN.

I'm experiencing frequent crashes, which TAC diagnoses as known-issues and
promises a fix will come in a future release (notice my once-every-6-months
crash got upgraded to a 'once-every-2-months-crash).  Is anybody running a
setup similar to mine that could comment on what I can do to increase the
stability of this unit, or am just living too close to the bleeding edge to
expect stability?
