Symptoms


SAP Adapter on OSB generates stuck threads, thus causing the weblogic server to go to "Warning" status, here is a sample of the stuck thread captured by weblogic:

<Error> <WebLogicServer> <BEA-000337> <[STUCK] ExecuteThread: '13' for
queue: 'weblogic.kernel.Default (self-tuning)' has been busy for "693"
seconds working on the request
"weblogic.work.SelfTuningWorkManagerImpl$WorkAdapterImpl@64d988",
which is more than the configured time (StuckThreadMaxTime) of "600" seconds.
