Frank Rizzo commented on AXIS2-4424:
------------------------------------
We are seeing the exact same issue but with the Sun 1.5.17 JDK.
How does the StAX implementation enter into this? Is this a known issue?
Thanks.

> We are continuously sending the SOAP requests to our server, after some time
> some of the threads will get into following stack trace. The number of
> threads which falls into the following stack trace will be increase with the
> time. Once 3 to 4 threads are fot into the below stack trace the server CPU
> will reaces to 100%. We debugged the issue and find that the problem is with
> the below method
> org.apache.axiom.soap.impl.builder StAXSOAPModelBuilder
> Method:
> public SOAPEnvelope getSOAPEnvelope() throws OMException {
> while ((envelope == null) && !done) {
> next();
> }
> return envelope;
> }
> In some specific conditions, the while loop never ends which resulted into
> 100% CPU.
> We enabled the TRACING and found that, once any thread falls in the this loop
> getting following statement in log file continuously.
> Please note that, there is not issue with SOAP request which we are sending,
> we tested the SOAP requests individually and all are getting proper response.
