a few people have reported similar problems with LVS-NAT.
It's not happening with LVS-DR. We don't have a solution yet (I don't
think anyone has a fix on the problem). This didn't happen in older
kernels
(2.4.x) and we don't know when it appeared in the 2.6.x kernels.

other people have reported 1 event in 6hrs (I seem to remember)
with a heavily loaded server.
