Thousands of Atomikos threads in TIMED_WAITING state

We have a JVM that has thousands of threads in TIMED_WAITING state just like this:

"Atomikos:10027" daemon prio=6 tid=0x0000000026590000 nid=0xd684 in Object.wait() [0x00000002df5df000]
  java.lang.Thread.State: TIMED_WAITING (on object monitor)
    at java.lang.Object.wait(Native Method)
    at com.atomikos.timing.PooledAlarmTimer.doWait(
    - locked <0x000000078b9ca0f0> (a java.lang.Object)
    at java.util.concurrent.ThreadPoolExecutor.runWorker(
    at java.util.concurrent.ThreadPoolExecutor$

  Locked ownable synchronizers:
    - <0x0000000789bd7c80> (a java.util.concurrent.ThreadPoolExecutor$Worker)

We are using version 3.9.2, with Tomcat 7

What could be the reason for this?

You probably have thousands of transactions ongoing?

Not sure if that is normal, contact support at to find out...
