Jean-Marc Lamond commented on AXIS2C-1650:
------------------------------------------

Hi Alex,
I have wrote an axis2c client gateway program for a legacy system.
I basicaly use cientapi for http/https native rest call, no soap. I use libxml2 because of
decoding problem with the local one.  I also implement xpath query (so far about 300 per invocation.
 
I have so far apply most latest patches, and so far, I still have few memory leak in transport,
but acceptable for a 10 000 times loop from the legacy caller.
I have so far digg out up to axiom_xpath_evaluate_streaming and corresponding axiom_xpath_free_result.
 Here is quite bad. A lot of memory is not release...
