java.lang.InterruptedException encountered under load

vince.adamo Oct 30, 2014 4:22 PM

I am load testing a web application running on JBoss EAP 5.2.0, with Seam 2.2.2 Final, and under moderate load (50-60% CPU utilization) I observe occasional exceptions like the one provided below. In summary, the initial UndeclaredThrowableException is being caused by a java.lang.InterruptedException that is being thrown while trying to acquire a Semaphore within the jboss EJB3 framework.

I would ideally like to understand what exactly is causing this interrupt. Is it a timeout that has been configured on stateless/stateful pool, transaction timeout, timeout waiting for a bean to become available, etc? There is no other message that is logged that provides a hint as to where I need to look to resolve this problem.

Any help would be appreciated!
