Whats your average CPU temp when running on a Pi3?

No standardized.
Show the amount of mem (you unfortunately seem to just have removed that info). It was 1400M or the like. That’s twice as much as it should be (unless you installed 64bit Java, but you didn’t, did you ?), so you likely have a memleak. Slowly remove bindings one by one until mem usage stabilizes.
In general, give way more information upfront if you want help:
