The messages themselves just mean that the RPC layer is congested, and
that a backlog of messages waiting to be sent is building up. Whenever
one of these messages times out, it issues the 'task xxx can't get a
request slot' error.
The question then arises as to why the RPC layer gets congested when
accessing your own nfs server. I have no problems with this on my own
machine, so I would first and foremost suspect amd. Can you repeat the
problem using just the stock NFS client + server?
