Yohan Liyanage commented on JBCACHE-1332:
-----------------------------------------
We are facing the same issue on JBoss 4.2.3.GA, running on Sun JDK 1.6 on a RHEL 5.3. JBoss is clustered with two nodes.
We are using the JBoss cache version shipped with JBoss 4.2.3, which is,
Version: 1.4.1.SP9
Codename: Cayenne
CVS: $Id: Version.java 5474 2008-03-27 21:49:43Z jiwils $
History: (see http://jira.jboss.com/jira/browse/JBCACHE for details)
So I assume this is not related to JBCACHE-1316.
Here's a thread dump I have taken from our servers.

> Project: JBoss Cache
> Issue Type: Bug
> Security Level: Public(Everyone can see)
> Components: Eviction
> Affects Versions: 1.4.1.SP1
> Environment: JBoss 4.05
> Hibernate 3.2.6.ga
> Reporter: Nicolas Lebreton

> JBoss TreeCache is used as cache provider. Please find attached jboss-service.xml configuration file.
> The second level cache is actitated, and several read-only classes are cacheable:
> <cache usage="read-only"/>
> The query cache is activated, and few queries are cacheable:
> <query name="ActorType.listAll.named" cacheable="true">
>
> We encounter an issue. It can be reproduced on an environment with only few users connected (less than 10). For those users, screen is refreshed every 30 seconds through Ajax requests.
> Application is running in a cluster. On the other hand, this issue occurs with only one node started. A JBoss is started. Less than 24 hours later, application is becoming unresponsive. JBoss then needs to be recycled. And it works.
> Before stoping the node, I have taken several thread dumps separated by at least 30 seconds. Please find attached 10th, 11th, 25th's output files. We noticed thread locks in these 3 snapshots. The stack trace of the culprit was always the same (please see attached outputs for more details):
