Samisa Abeysinghe commented on AXIS2C-540:
------------------------------------------
I assume you have done the tests with libxml2 parser.
If you use guththila parser, you will get less leaks.
Anyway we need to fix the leaks for libxml2

> Key: AXIS2C-540
> URL: https://issues.apache.org/jira/browse/AXIS2C-540
> Project: Axis2-C
> Issue Type: Test
> Affects Versions: 0.96
> Environment: Windows XP
> Reporter: markus mayer
> Priority: Critical
> Attachments: Axis2MathMemLeakSample.jmx, patched_ApacheJMeter_http.jar
>
>
> This is a follow-up to my post regarding memory-leaks on axis-c-dev (original
> message attached below). the test-tool i used for my tests is apache jmeter
> (http://jakarta.apache.org/jmeter/index.html). i am using the current version
> 2.2. unfortunately the component for creating soap requests has a minor bug
> in its current version. it is creating http requests with
> "transfer-encoding: chunked". as it stands now the simple_axis_server does
> not handle this transfer-encoding, with mod_axis2 and apache it appears to be
> working. i am however not sure if simple_Axis_server is supposed to properly
> handle such requests. if
> it is i can open a jira for this.
> anyway i attach both a patched version of a jmeter library that addresses the
> "chunked" issue (hopefully without introducing a host of new ones...).
> instructions (after download/setup of jmeter 2.2):
> - copy the jar to [jmeter_main_dir]\lib\ext.
> - replace the original apachejmeter_http.jar.
> this should work. i also attach the test suite i used (the .jmx file). it
> simply calls the add method of the math web-services with 5 concurrent
> threads.
> i hope this helps you guys to reproduce my results.

> Hello,
> A couple of your postings during the last days were concerning memory leaks
> within \
> axis2c. I used a load testing tool to run a simple suite consisting of the
> concurrent \
> invocations of the math sample web-service (the add service method).
> In case you are interested find my results below (values are taken from
> windows \
> process view column "mem usage"):
> - axis2_http_server doubles its memory usage after approx. 5000 requests
> (from \
> initially 5.5 megs to approx. 10 megs)
> - when using mod_Axis2 with apache2 (2.0.59) the situation is as follows:
> initially the server takes about 13 megs of memory. after 1000 "add" requests
> apache \
> went up to 40 mb of mem usage and kept increasing steadily.
> - when using apache2 ver. 2.2.3 the situation is almost the same.
> If you are interested in investigating these issues further I can provide you
> with \
> all the details about test-tool (jakarta jmeter), test-suite,etc.
> I think especially fixes for the apache mod would be particularly
> important/helpful \
> for 1.0 as this is the suggested deployment scenario (i assume?). Bye,
> Markus
