We are using JBoss 4.2.3.GA with Java 1.5 and we recognized that number of handles consumed in windows is rapidly increasing ending with server crash. We found that problem is mainly in jgroups.jar and after upgrade of that library problem seems to be almost eliminated but still there. In other words we have still "handle count" increase even when no application is deployed which can indicate thread leak. Does anyone have same or similar experience?
