    NFS server error reply Unknown rpc response code with tcpdum

    This is message log error with tcpdump on nfsserver1. (When access shared directory from nfs client)

    Code:
    tcpdump host 192.168.11.6 | grep Unknown
    tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
    listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

    Some time nfs client is slow. How to monitoring and performance tuning.
