Symptoms

On OFSAA 8.0.3, with WebLogic Server Version: 12.1.3 and with the new version of 8.0.3 there seems to be an issue with stuck threads or more specifically Hogging Threads. The threaddumps.log shows the following errors for STUCK threads:

ERROR

"[STUCK] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'" daemon prio=10 tid=0x00007f0ce4002000 nid=0x7b0c in Object.wait() [0x00007f0d379e9000]

Not able to narrow down what is occurring but these hogging threads are coming from the WebLogic JVM for the OFSAA EAR. OFSAA is operational for the most part but there are screens that are surprisingly slow.

The issue can be reproduced at will with the following steps:
1. Upgrade to 8.0.3
2. Find STUCK threads

Changes

 Upgrade to 8.0.3.
