We just converted some point to point interfaces from STAR to Horizon Clinicals. When these systems are in a point-to-point configuration the messages fly between systems. When the engine is inserted, the STAR system backs up to the point where it is sending at approximately 1 message per second… Really slow… The route is a static raw. Cloverleaf System is AIX 5.2 with Cloverleaf 5.3. In a matter of minutes we had over 700 messages backed up on STAR. When we converted back to point to point, they were gone in around 20 seconds. Any ideas…..
