5.1 Stuck Thread Errors and Tuning Parameters

The health status of the soa10_server (SOA managed server) may show a warning message due to Stuck Threads.

If you go to managed server->Monitoring->Threads from admin console, you will notice after browsing through all the threads that a few threads may be reported as stuck.

ESB uses Work threads for queueing and dequeueing from ESB topics. If these threads are inactive for more than 600 seconds they are considered "stuck' by Oracle WebLogic Server. Since ESB does not release these Work threads for the lifetime of the Server, the above errors are expected and benign in nature.

The stuck threads max time can be increased for the managed server from the managed server->configuration-tuning menu.

Increase the Stuck Thread Max Time parameter to a large value (for example, 2147483647 seconds) to delay Oracle WebLogic Server indicating that the threads are "stuck".
