> Unhandled Exception when using Gnuthilla
> ----------------------------------------
>
> Key: AXIS2C-717
> URL: https://issues.apache.org/jira/browse/AXIS2C-717
> Project: Axis2-C
> Issue Type: Bug
> Components: guththila, platforms/windows
> Affects Versions: 1.1.0
> Environment: Windows XP Professional SP2
> Apache 2.2.4 server with Axis2c 1.1.0 module
> - Remote stress test client script hosted by Fedora Core 7
> Reporter: David Klassen
> Assignee: Dinesh Premalal
> Fix For: 1.2.0
>
>
> I wanted to stress test axis2c deployed on apache, to see if using this SOAP
> implementation would be reliable. Simulating 25 concurrent users (with a
> shell script) making one request per second by using the 'echo' sample
> program (recompiled to target the server from a remote machine[Linux]). With
> Gnuthilla compiled-in axutil.dll suffered an Unhandled Exception
> (repeatably). While Gnuthilla did suffer less memory consumption, when the
> httpd.exe memory consumption reached around 77 MB the exception was
> triggered.
> Here is what my VS 2005 debug session provided me:
> < non-debug modules excluded >
> 'httpd.exe': Loaded 'C:\cygwin\thirdparty\axis2c\lib\axis2_http_sender.dll',
> Symbols loaded.

> Seeing that this is a thread, I cannot be sure if the error was triggered by
> apache or something else. I guess this might be something apache specific? It
> is interesting to note however that this happens consistently with gnuthilla,
> whereas without it a crash does not always occur (ie. Only some of the time).
> Without gnuthilla the httpd.exe process sometimes reaches 200 MB or more
> without crashing. Still trying to figure out what causes the net memory
> consumption, since even when the 25 clients are stopped the httpd.exe memory
> size does not decrease.
