My jboss server got several slow responses. I read from a passage that, it may due to the lack of Thread pool connection. However, that post suggested I can monitor the QueueSize in the JMX MBean first, if the QueueSize reaches the maximum thread pool size, I have to increase the maximum thread pool size. However, when I have a load test and monitor the QueueSize, the result is always 0. Is there any problem for reading the QueueSize?
