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.

Any help in this regard is appreaciated.

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.
