WTC: "weblogic.wtc.gwt.TuxedoConnection.tpacall()" Was Blocked By "java.net.SocketOutputStream.socketWrite0()" (Doc ID 2207439.1)

Last updated on MAY 08, 2023

Applies to:

Oracle WebLogic Server - Version 10.3.6 to 12.1.1.0
Information in this document applies to any platform.

Symptoms

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.
