I am using a BeanManager to acquire classes annotated @Stateless in multiple threads. This worked fine in 7.1.3, but now in 8.0.3 I'm receiving this error:
javax.ejb.ConcurrentAccessTimeoutException: No instances available in Stateless Session Bean pool. Waited 30 SECONDS I see a number of these exceptions until the machine roughly runs out of memory and restarts (though there's never an OutOfMemoryError in logs). I had encountered this error in the past and solved it completely by increasing the maxSize to 20 in tomee.xml: <Container id="StatelessContainer" type="STATELESS"> maxSize = 20 </Container> Is there any reason that I would need to boost this value in tomee 8 compared to tomee 7? Or any reason the memory footprint would be different enough to cause a crash. No other differences, same configuration Thanks, -Kean
