Software :: Nfs-kernel-server Out To Lunch ?

Code:

My NFS client keeps timing out like shown above. It has been working fine for months, up until today. I had a share mounted as "default,udp" so tried removing the udp option. (I mainly use it for streaming content.) The problem persists. nfsstat returns no useful info, nor is there anything suspicious in the server's logs about nfs. On the client, the only thing an rgrep on /var/log returns is what I've included above -- and there are pages and pages of it. No packets are being dropped and the network is otherwise stable. tx/rx over all other protocols has been fine.
