I've got a network trace of communications w/ that client+server, and what's going on is the client is sending two FetchStatus requests (one against each volume), and the server is sending back a RX abort packet. Nothing but that over and over again.

that was fixed in (I think) 1.2.2 after Jimmy Engelbrecht complained about

by the fileserver.

Why not try the upgrade first, then worry about instrumentation if you
still have a problem?
