parallel_for and thread_monitor::launch: _beginthreadex failed

Hi I've just recently been having trouble running parallel_for loops. I'm using TBB as part of Parallel Studio XE 2017 Cluster Edition. With no changes to my code, I have been receiving the error message thread_monitor::launch: _beginthreadex failed whenever my program reaches my parallel_for loop and crashes my program. This recently has also been happening to my other projects too. My project involves capturing images with multiple cameras with each camera running in parallel with each other.

What is : Unexpected exception or cancellation data in the masters dummy task

When I get this message as part of an assert / abort ...

"Unexpected exception or cancellation data in the masters dummy task"

What is a likely cause ?  What tricks might I used to try to diagnose this further and maybe find the 

root cause ? 

It sounds like a master task has been unreasonable about allowing a task to finish gracefully,

but that's just a guess on my part.

Any hints or elaborations or guesses would be appreciated.
