Exception when running load test

Hi ,

I have a simple 2 req/resp test case and trying a load test with 10 threads.
I am using a mock service to test this.

I get the following exception even if i run with just 1 Thread.

I also see the following exception when I increase the number of threads to about 50. In both cases I dont give any time delay between threads and the Startegy is Simple.

    Hi,

    hmm.. have you enabled Coverage for the MockService? Try enabling or disabling it to see if that helps.. alternatively try disabling the MockService log.. sounds like a bug otherwise..

    regards,

    Ole,

    If I disable MockService coverage, this error does not show up.

    Thanks.

    The MockServiceLog is already disabled ( I presume).
    I get the following logs.

    Thu Aug 07 09:24:04 BST 2008:INFO:Disabling logs during loadtests
    Thu Aug 07 09:24:06 BST 2008:INFO:Enabled logs after loadtests


    However, I have unearthed a couple of others.

    When I open the MockService Options dialog I get the following Exception.

    And When I opened the load test screen and started it the first time, the following stack appeared on the 'MS-DOS' window that opened the UI.
