IBM C9510-401 - D Application Server Network Deployment V8.5.5 and Liberty Profile System Administration

Problem(Abstract)

The SystemOut.log contains a WSVR0605W message, also called a hung thread message. A javacore, or thread dump on Solaris and HP-UX, is needed in order to determine how to resolve the potentially hung threads.

Cause

WebSphere Application Server attempts to report potentially hung threads using the hung thread detector. Depending on how the hung thread detector policy is configured, a thread running for a certain interval (default 10 minutes) might be reported as hung and a WSVR0605W message is printed in the SystemOut.log file:

WSVR0605W: Thread has been active for and may be hung. There are in total in the server that may be hung.
