I'm using TomEE 7.0.4, EJB version 3.1 I often see this when making a high volume of calls to methods in @Stateless classes:
javax.ejb.ConcurrentAccessTimeoutException: No instances available in Stateless Session Bean pool. Waited 30 SECONDS I've set maxSize to 1000 in my tomee.xml and I still receive the error just as soon as I would without maxSize specified at all, which leads me to believe it's not doing anything. I see recommendations on this list to use @Singleton with a read lockmode, but that doesn't seem to make a lot of sense with our current arrangement. Thanks! -Kean
