NFS network load on 5.4-STABLE

[Mike Eubanks]

As soon as I mount my NFS file systems, the network load increases to a
constant 80%-90% of network bandwidth, even when the file systems are
not in use.  NFS stats on the client machine (nfsstat -c) produce the
following:

Fsstat and Requests are increasing very rapidly.  Both the client and
server are i386 5.4-STABLE machines.  Is this behaviour normal?

/etc/rc.conf
------------
rpcbind_enable="YES"
rpcbind_flags="-h 192.168.11.200"
nfs_server_enable="YES"
nfs_server_flags="-h 192.168.11.200 -u -t -n 6"
mountd_flags="-r"
