"df" command hangs on NFS mounts. Root attempts to "su - <user>", but this also hangs. It looks like the NFS server is not responding, but this is not the case -- we have many other servers using the same directories via NFS, and response is fine. Monitoring on the NetApp show it is running well. /var/log/messages has this: Aug 7 09:55:42 copperhead klogd: ------------[ cut here ]------------ Aug 7 09:55:42 copperhead klogd: kernel BUG at net/sunrpc/rpcb_clnt.c:290!
