Affects Version/s: 0.96
Fix Version/s: 1.1.0
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.

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,
