Hey Guys,

I think I have my issues resolved as well. Our issue turned out to be the NetXen-based 10GbE NICs. They were HP NC510C cards (Single Port CX4).

Once these cards were replaced with Intel 82598EB-based cards by SuperMicro the LUN dropping has disappeared and all VMKernel logs and DSS logs look clean and clear.

I will keep you guys posted with test results once I get my balance-rr setup on the 2-port NICs.
