Hi team,

We've been suffering OutOfMemory intermittently in our test labs recently. The call stack is below

Our test case count is +4k and still increasing, and pass rate is around 95% for each execution. The OOM error is not always reproducible. And we set memory dump parameters, but there is no dump file generated when it occurs. 

The line of code throwing the exception is below.
