Concurrent Load Exception

Friends,

I am receiving the following exception reproducible consistently;

This exception is seen to occur exactly as I start more than 10 concurrent executions by using the Run Once feature in SOAP UI Runner. This happens exactly the same way even if I use a generator.

Any pointers. Please help.
