[ERROR] NAKACK.handleXmitReq()

Hi all,

I tried to run the perf_test in three 2-way Solaris 10/x86 machines
but I got a lot of error messages
like the following:

806928 [ERROR] NAKACK.handleXmitReq(): - (requester=10.50.4.37:7800,
local_addr=10.50.4.38:7800)
message 10.50.4.38:7800::2702582 not found in sent msgs.
Sent messages: [2706596 - 2742395] (35800)

Can someone explain to me how to avoid them.

Here there are the HW and configuration details:
