Hi,
We have many Jboss servers talking to each other using EJB 3.0 (SLSB).
Now that the servers are getting very busy, we are having problem with Jboss creating too
many Threads.
At some point, we have an exception when it can't create native Threads anymore.
It seems to be due to remoting as it does happens when we do load testing from the
client.
looking at the jboss web-console, most of the Thread are as follow :
*
*
*Thread: Timer-896496* : priority:5, demon:true, threadId:1114825, threadState:WAITING,
lockName:java.util.TaskQueue@4c8113f8
java.lang.Object.wait(Native Method)
java.lang.Object.wait(Object.java:485)
java.util.TimerThread.mainLoop(Timer.java:483)
java.util.TimerThread.run(Timer.java:462)
*Thread: Timer-896497* : priority:5, demon:true, threadId:1114826,
threadState:WAITING, lockName:java.util.TaskQueue@6d5199b5
java.lang.Object.wait(Native Method)
java.lang.Object.wait(Object.java:485)
java.util.TimerThread.mainLoop(Timer.java:483)
java.util.TimerThread.run(Timer.java:462
They are found under the group :
*Thread Group: main* : max priority:10, demon:false
*Thread: DestroyJavaVM* : priority:5, demon:false, threadId:9,
threadState:RUNNABLE, lockName:null
*Thread Group: jboss* : max priority:10, demon:false
Any idea how we could get rid of these Thread or limit the time they live ?
Thanks.
Sebastien
