Description:
============
In a multi-engine BusinessConnect (BC) instance, the primary and standby engines of a BC fault tolerant cluser continually activate and  deactivate during the day.  What can cause this?

Environment:
==========
TIBCO BusinessConnect Protocol 5.X.X all versions

Cause:
=========
The Fault Tolerance (FT)  heartbeat messages are getting "lost" on your RV network.  

Resolution:
=========
The FT messages are sent and received on the RV network specified under the "Fault Tolerance" tab of the par file under Administrator&gtApplication Management&gtBusinessConnect&gtConfiguration&gtInteriorServer.par&gtFault Tolerance tab.  If you are not using a multicast network specification in the "Network" parameter, consider configuring this parameter to use one.  Instructions for how set this parameter are in the Rendezvous manual set.
