NFS problems with RH 7.0 on PowerEdge 2300

We have had an increasing problem with our PowerEdge system suddenly locking
up. An examination of /var/log/messages indicates that the problem appears
to be with nfs. The system ran a long time with no problems but this nfs
problem has now made the system very unstable. Our 2300 is primarily a
fileserver for our network which has a Sun Netra running Solaris 5.6. Has
anyone else encountered this problem? Here is the messages file output:
