ooo... you may have nailed it there. I was definitely over the 75%. I bumped up my overall system RAM, and then locked in the one site that isn't used too much to a lower value. Its early, but so far no crashes. Interesting that Java 8 never had an issue with this, but 11 clearly is. Hopefully this holds as a solution. Thanks for the tip!
