i assume , your nfsserver is OK ,at the now try some issues on the nfs client

* check traffic between nfsserver and your client
Code:
# tracepath nfsserver

or try nfswatch
Code:
# yum install nfswatch && nfswatch -dst nfsserver -src nfsclient

* try to boot with newer kernel and check your messages
Code:
# rpm -ivh kernel-newer.rpm && tail -f /var/log/messages

* check the nfsmount parameters(tmeout and rsize/wsize) and if you still problem then change your settings according to Optimizing NFS Performance
Code:
# nfsstat -m

which version of NFS is running? How many daemons is it running (if v3?) how much memory does this machine have, and what are your mount parameters? Have you considered cachefilesd on the client? Are you sure you are not using UDP?
