Memory Increase & Crash with Basic Example on Repeat

I'd like to understand why memory increases until a crash happens when running even basic examples from the TestStand Editor or User Interfaces.

For example, if I modify the PreUUT of the Computer Motherboard Test shipping example to run indefinitely, TestSTand memory will increase until a crash occurs - at around 500 MB.

 
What is causing the memory to increase?

Also shouldn't it take more than 500 MB to make TestStand crash with reasonable PC specs?

TaskManager.vi in this solution allows memory to be cleared up and can prevent the crash:
