Hi, We are using WebLogic 9.2.2 with Java 1.5. The application is written
using Struts 1.3 and log4j 1.2.15. We found a number of errors that looked
like below in our managed server's .out file. Any ideas what might be a
cause or how to troubleshoot further? Our sys admin sadly did not preserve
a thread dump:
<Jun 30, 2009 3:00:11 PM UTC> <Error> <WebLogicServer> <BEA-000337>
<[STUCK] ExecuteThread: '148' for queue: 'weblogic.kernel.Default
(self-tuning)' has been busy for "604" seconds working on the request "Http
Request: /myapp/hhFlow.do", which is more than the configured time
(StuckThreadMaxTime) of "600" seconds. Stack trace:
Thread-135888 "[STUCK] ExecuteThread: '148' for queue:
