The strange thing is that this happens every time after a long period
of inactivity. So the first whatever access to the filesystem fails
in this manner *every time*. Subsequent access is alright. Network is 
a local gigabit switch and, altough not impossible, 'a network issue'
does not sound too plausible to me. The machine is being used plenty
for other tasks without problems.

So there is a timeout, but whatever the cause is, it's triggered by long
term inactivity. We never had any network problems.

Other machines that access the filesystem on a regular basis do not show
this problem. It's only the machine that get's used once in a while.
The problem is reproducable, not a one time event.
