NFS tcpdump give rpc reject messages


Hi,

NFS share is getting lot of RPC reject logs. which makes IO on NFS share very slow and sometimes CPU Load goes very high due to this.

tcpdump -s 0 -n -i eth1 | grep reason
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth1, link-type EN10MB (Ethernet), capture size 65535 bytes
