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.
