Applies to:Oracle WebLogic Server - Version 10.3.6 to 220.127.116.11
Information in this document applies to any platform.
WebLogic Tuxedo Connector sub-component, with Oracle Service Bus(also known as OSB)
The following STUCK Threads are occurring:
Came to the point that the WLI servers, for OSB, were not responding at all as a synchronized SocketWrite() operation never did wake up (might be because remote machine DOWN/CRASHED, TCP window full mechanism, Firewall misconfiguration, ...).
Resulted in the application server spawning more and more threads. All threads hanging on the synchronized SocketWrite operation.
