JVM not getting enough memory in the container

[carueda]

@brandonnodnarb thanks again for the testing and exposing this issue.

@lewismc / @graybeal FYI

As indicated on slack, I suspect the issue is not enough memory given to the JVM, even though the container itself has plenty.

Below are some snippets from the log and some ctop screenshots.

There're several references out there related with JVM resource use within containers ... I explored some quite a while ago, and one recent finding now that may be useful is this.
