Symptoms

In Oracle Service Bus (OSB) the following flow has been implemented:

OSB Proxy service1 (sb or jejb) - route -> OSB Business service1

• All OSB services have custom work managers (Dispatch Policy) associated.
• "OSB Proxy service1" and "OSB Business service1" are using the same work manager.

Under load, when max capacity of work manager used for Proxy service 1 and Business service 1 is reached, stuck threads are seen. This can happen with proxy services using synchronous inbound transports like sb or jejb.
