when i read this, nfs was the first thing that popped into my mind also. second would be a network outage. i have experienced the exact symptoms, but on static nfs mounts, after i have brought down the server for extended periods, or the net is out for long periods, then a client will do this. i simply recover by umounting then doing a mount -a. hth >> I can't think of anything which has changed on the affected systems. >> Since they're running FC5 nothing is getting updated.
