Was the client actually attempting to mount or unmount?

The servers were running for a while, thus, as far as I know my setup,
there is no ongoing mount or unmount. Moreover none of the clients were
rebooting, starting or shutting down.
Interesting. I would therefore suspect the create_session was simply a
reconnect after some kind of transport connection error/loss, and the
destroy_session callers are hung for the same reason. And I agree with
Chuck that a network trace will help identify the patch which is needed
here.

You may have to let the trace run for a minute or two to detect all the
retry traffic between the client and server threads.
