                 Key: AXIS2-5666
                 URL: https://issues.apache.org/jira/browse/AXIS2-5666
             Project: Axis2
          Issue Type: Bug
          Components: client-api
    Affects Versions: 1.5
         Environment: Websphere Application Server 6.1, Linux OS
            Reporter: Kishore Guruswamy

Hi 

We are using Axis2 1.5 version to invoke web services.

We are seeing a large number of Timer threads (Timer-1, Timer-2...) build up, eventually causing
the Production application server to run out of memory.

All of the timer threads are in wait condition

"Timer-110" Id=555 in WAITING on lock=java.util.TaskQueue@3e203e2
    at java.lang.Object.wait(Native Method)
    at java.lang.Object.wait(Object.java:231)
    at java.util.TimerThread.mainLoop(Timer.java:534)
    at java.util.TimerThread.run(Timer.java:487)

To resolve the issue, We have leveraged the cleanUpTransport() method in the service client
and also leveraged the Reuse Http Client option.

However, the issue still persists.

Looking for some insights on resolving the issue.


Thanks
Kishore G
