I'm not disputing the merits of NFS/TCP. I suggested this merely as a workaround, and to see if the bug in question is causing the hangs. > Wouldn't it be better to fix the bug? Is there a problem report on this? Of course it would be better to fix the bug. But until someone fixes it... There's no problem report on this. I can only speculate as to why the restart clears this up. The restart shuts down existing NFS/TCP connections. This will force the client to reconnect, causing it to recover. mohan
