> 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
