Local fix

Problem summary

  • The problem occurs when the following all occur:
    If a node is restarted quickly and low numbered RTP pipes are in
    use at the point that the node is stopped (eg @R000004) then a
    VRN partner will not detect the failure and when it polls after
    the VRN connection is re-established CS/AIX can mix up the old
    data with data from a new partner. This leads to the ASSERT
    (which detects the randomised TCID that CS/AIX generates).
    

Problem conclusion

  • Code has been added to ignore the old data.
    

Temporary fix
