Farming skulks in SS ... crashing like clockwork every 20m

I CTD almost every 20 minutes. I've been farming skulks inside their campsite for an Ethereal Armor V Tech, never even stepping out of the camp. It seems about 20 minutes after logging back in, I crash again.

Haven't seen anything as obvious as say when you are turning in trophies and the client hits the memory allocation limit. That's like clockwork too, but at least you can see it happening. This case is not so easy.

What is not being unloaded here if I am staying within the same 50m area? The clients process hasn't shown nearly as high of usage as I've seen in other cases where you can expect it to crash (and then it freezes up, not immediately to desktop).
