WebService A making call to another WebServer B fronted by Oracle Service Bus (OSB) and an Apache WebLogic plugin loadbalancing OSB servers. Here is the call path
WebService A (HTTP Post) -> Apache in front of OSB -> OSB Cluster (ClusterCapacity = 8) -> WebService B (Business Service)
Problem: Only one OSB server in the cluster is taking the complete load originating from WebService A.
WebLogicBridgeConfig page shows all the 8 servers active with no errors and these 8 servers are actually taking the load serving other business services which is font ended by the same apache plugin.
Environment: Apache 2.2.x, Oracle Service Bus 10gR3.
Platform: RHEL 5.x
