Right this is what I have already done, using gnuthilla and without
gnuthilla. Unfortunately using mod_axis2.so with v1.1.0 or v1.0.0
causes the size of httpd.exe to grow continually. I decided to post
bug *AXIS2C-717 <https://issues.apache.org/jira/browse/AXIS2C-717>*
detailing where the memory of httpd.exe kept growing and eventually
encountered an unhandled exception.
Please note that, even though there seems to be a growith, if you keep
on sending requests, you would notice that, at some point, it drops
back. This is dues to the pooling behaviors of apache. I cannot recall
an exact number, after which it would drop, possibly you have to send
few hundred requests.
