Hi Tim, After quite long time, I got the thread dumps. I attach only one of 'master' ActiveMQ machine. thread_dump.log <http://activemq.2283324.n4.nabble.com/file/n4725874/thread_dump.log> Here are weird info I noticed from thread_dump: - There are 4955 threads in WAITING state. - Most of them (4917 threads) comes from org.apache.activemq.thread.DedicatedTaskRunner.runTask. - There are 4899 threads relate to a queue/topic mq1-42989-1493220210257-1:1:xxxx
Do you have any ideas from this thread dump? I wonder if my trouble would be solved if UseDedicatedTaskRunner disabled?
