So, nxagent thinks it hasn't received any data from the client in 30s, and shuts
down. I've seen this sort of thing before, with both neatx and NoMachine's 
nxserver.
It comes down to either a network issue, or a bug in nxserver, but we were 
never able
to prove anything conclusive either way i'm afraid.
