BEA-000337 StuckThreadMaxTime with OSB FileAdapter

20-Jan-2011 10:57:20 o'clock WET Error WebLogicServer BEA-000337 [STUCK] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)' has been busy for "602" seconds working on the request "weblogic.work.SelfTuningWorkManagerImpl$WorkAdapterImpl@57134e4b", which is more than the configured time (StuckThreadMaxTime) of "600" seconds. Stack trace:

I keep getting this error.

Besides, the number of Stuck Threads increases with time, all of them are weblogic.work.SelfTuningWorkManagerImpl$WorkAdapterImpl@blablabla

Another stack trace is:


oracle.tip.adapter.file.inbound.PollWork.run(PollWork.java:369)

Here it solves the problem:

http://blog.easyteam.fr/2010/10/18/osb-%C2%AB-stuck-threads-%C2%BB-sur-la-consommation-de-fichiers/


basically it suggests to create a WorkManager "FilesPollingWorkManager" for the FileAdapter polling thread and setting "Ignore Stuck Threads" to true, and assigning this FilesPollingWorkManager as "Dispatch-Policy" to the File Polling Proxy Service
