Actually, I get similar on our system(s) for very large directory
structures ... I've changed my scripts so that it times out after 15
minutes and re-tries up to 5 times before considering it a failure, which
appears to have 'gotten around' the problem ...
When it hangs, i've tried setting truss -p again both the server side, and
receiver, and nothing seems to be happening on the server, and periodic
'select()'s happen on the receiver ...
