This machine has a long and faithful service record, although of course that doesn't rule out hardware failure. I can try to dig further into this process to find out exactly what is triggering the hang. But, so you know, I switched the mount to UDP (rw,udp,nfsvers=3,rsize=32768,wsize=32768,intr,hard) and now the process completes normally. Not being a kernel developer, I do wonder why a single piece of corrupted data can have the effect of hanging the mount for all users and all processes. It also creates an unkillable process, requiring the machine to be rebooted, relating to the 'unmount -f' discussion that's been going on here lately. > > Try using the eepro100 driver and/or a different card. Swapping cards not so easy, this is a motherboard with built-in ethernet. I can try the eepro100 driver though. thanks, andrew ------------------------------------------------------- This SF.NET email is sponsored by: Thawte.com Understand how to protect your customers personal information by implementing SSL on your Apache Web Server.
