AXIS 1.1 stuck in HashMap.get during the load

I've run a soap request under the load.

and at some point after the peak response come through, the rest of requests going to infinite loop with the following stack trace.

have anyone experience this kind of issue before?

this looks similar to AXIS-2498 but the stack trace is different.

Appreciate if someone can guide me through this issue.

Thanks
