>     Versions: 0.92
>  Environment: Fedora Core 4 running kernel version 2.6.12-1.1456_FC4

> When invoking a web-service through multiple threads after a few requests an error occurs on the server. The full stack trace from Tomcat is appended below.
> To simulate the problem you need to deploy the service attached to this jira issue ["TestService.arr"], and run the ant goal to test the system[All testing code is present in the "testing_code.zip" which is attached]. To run the ant goal you will have to modify the build.xml file according to your system. The number of threads the test operates on and the total number of tests to be run can be controlled through the build.xml file. After modifying the build.xml file run "ant run" to run the tests.
