-----------------------------------------
Dear Andreas,
Thank you for your response. We are not able to figure out the request that is
causing this issue. Can you please let us know how we can enabled logging in
Axis 1.5 so that we can capture that request?
This is happening on our production server which is accessed by many clients.
We are not sure this client is send a request.
Regards,
Ishwardeep
