WPT Driver crashing

[jedmichnowicz]

I recently setup some private instances in AWS on Win server 2012R2. After a period of time, all agents will eventually drop off. After RDPing into the instance, I will see WPTDriver starting up making me think it has crashed at some point. These are m4.large instances.

Looking through logs, I see numerous "app crashes" for Flash on Firefox and some resource exhaustion warnings.

Is it possible the flash and/pr resource exhaustion issue are killing the WPT driver? Any ideas what might be wrong?
