> Nightlies reporting OutOfMemoryError: unable to create new native thread

> Chatting w/ Nick and Huaxiang, doing the math, we are likely oversubscribing
> our docker container. It is set to 20G (The hosts are 48G). Fork count is
> 0.5C on a 16 CPU machine which is 8 *2.8G our current forked jvm size. Add
> the maven 4G and we could be over the top.
> Play w/ downing the fork size (in earlier study we didn't seem to need this
> much RAM when running a fat long test). Let me also take th ms off the mvn
> allocation to see if that helps.
