Hi Leslie,

This is likely the same problem as was reported in https://bugs.freebsd.org/225054#c8, and fixed by the following patch:

https://svnweb.freebsd.org/ports/head/java/openjdk8/files/patch-hotspot_src_share_vm_services_memTracker.cpp?view=markup&pathrev=459368

Can you please try that out, and see if it fixes it for you too?
