Memory Leak in axiscpp 1.6b/xerces 2.6?
While working with axiscpp 1.6b (a nightly build from Dec, 2006) and
xerces 2.6, I noticed a memory leak of roughly 300 bytes each time my
server code calls the Axis SoapDeSerializer::getElement function. In
other words, each time one of the API functions I have written tries to
get its input parameters from the Axis/Xerces infrastructure, I am
losing about 300 bytes per input parameter.
I am deleting the parameters with AxisDelete after I am done with them,
so that's not the problem. Regardless of whether the input parameter is
a string/int/etc, the leak is basically the same.
I was wondering whether anyone else has noticed this, and if so, what is
recommended to fix it. Would moving to Xerces 2.7 help?
Thanks in advance,
-JB

Nadir,
After sending my e-mail, I decided to go ahead download the Xerces 2.7
and rebuild Axis and then rerun my tests. Amazingly, the memory leak
disappeared with Xerces 2.7...
The 2.7 Xerces documentation
(http://xml.apache.org/xerces-c/releases.html) mentions four separate
memory leak fixes in 2.7 - perhaps one of these was the one that did the
trick for us.
If anyone out there knows of any caveats regarding the use of Axis 1.6b
(SVN build - code taken from mid-December, 2006) and Xerces 2.7, I'd
love to hear them.
Thanks all, and have a good weekend,
-JB

Jonathan,
I would try building from the latest source code in SVN and see what
happens. Lots of changes have been made in the serializer. I doubt it is
the parser.
