Title:
  malformed nfs v4 compound packets

Status in “nfs-utils” package in Ubuntu:
  Confirmed

Bug description:
  lsb_release -rd
  Description:    Ubuntu 10.04.3 LTS
  Release:        10.04

  apt-cache policy nfs-kernel-server
  nfs-kernel-server:
    Installed: 1:1.2.0-4ubuntu4.2
    Candidate: 1:1.2.0-4ubuntu4.2

  We have a nfs v4 share which is mounted on multiple solaris 10
  clients. Sometimes one of the nfs clients can't open a file on the nfs
  share with the following error message:

  cat /m/local/tmp/nagios_check_nfs.chk
  NFS compound failed for server dbnfs: error 2 (RPC: Can't decode result)
  cat: cannot open /m/local/tmp/nagios_check_nfs.chk 

  After waiting some hours or remounting the nfs share it works again.
  The other clients can access the file without problems. I have
  attached a tcpdump of the network traffic: the ubuntu server is
  sending a malformed nfs compound package to the client according to
  wireshark.
