      HI,

           I wonder if anybody can help me with this issue. Recently I start noticing that number of threads in my Wildfly 8.2 keep growing and growing... when I run jstack I have noticed bunch of threads like this:

       

      "pool-16609-thread-1" prio=10 tid=0x00007f1d0327a000 nid=0x5433 waiting on condition [0x00007f1ad23a2000]
         java.lang.Thread.State: WAITING (parking)
          at sun.misc.Unsafe.park(Native Method)
          - parking to wait for  <0x000000059b1ae630> (a java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject)
          at java.util.concurrent.locks.LockSupport.park(LockSupport.java:186)
          at java.util.concurrent.locks.AbstractQueuedSynchronizer$ConditionObject.await(AbstractQueuedSynchronizer.java:2043)
          at java.util.concurrent.ScheduledThreadPoolExecutor$DelayedWorkQueue.take(ScheduledThreadPoolExecutor.java:1079)
          at java.util.concurrent.ScheduledThreadPoolExecutor$DelayedWorkQueue.take(ScheduledThreadPoolExecutor.java:807)

          at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
          at java.lang.Thread.run(Thread.java:745)
      

       

       

           Your help will be highly appreciated.

       

      Cheers,
