We are getting a lot of stuck thread in our production environment. We have to restart the server, once the queries are stuck. Basically we are using EclipseLink 2.4.1 in a J2EE stack with WebLogic 10.3.6. We often have a lot of "stuck threads", caused by lines in EclipseLink that are getting releaseDeferred locks in concurrency manager. using JPA

Have you gone through the http://wiki.eclipse.org/EclipseLink/FAQ/JPA#How_to_diagnose_and_resolve_hangs_and_deadlocks.3F FAQ? You will need to gather the thread dump, and it would help to look at what the code involved in the lock is doing, and evaluate the other threads as I do not believe this is a true deadlock.

In this case, two or more threads are operating on the same object graph, attempting to build or write to it at the same time. This thread that gets stuck is simply waiting for some other thread to finish building the object graph, and WLS is timing it out believing it is stuck. It maybe stuck, or you are just experiencing a bottleneck on a particular object or graph in the shared cache due to options (like read-only, always refresh or other settings) that causes thread issues under load or less ideal circumstances.
