Hi H.J.,

The RPC patch is effective only on the _server_ side, as the problem was that the
knfsd processes were getting wedged in the svc_recv() routine. Once the server
processes become stuck, the client side will eventually time out, leaving the socket
with a large read queue. This is then reported as a "socket destroy delayed" message.

Regards,
Bill
