That's not as interesting as which hosts are blocking the file server.  Some
things to check for:

file server is hung trying to talk to pts
file server is hung trying to recall callbacks from unresponsive clients

There may be clues in your FileLog.  I'd be suspicious of and  They are unreachable right now, at least from here.  If they
are doing thousands of Fetchstatuses but can't be reached by the file server
for callbacks, that could foul things up.  Is that subnet behind a firewall?

Your message was delayed to the list by a couple of weeks.  Is the 1.4.4
file server any better now than the 1.4.1?
