I have no doubt about this. That is why I booted the system this
morning and repeated the java -Xmx2560M test before any other
application stuff occurred - and it still fails.
Further, all of our other instances, similarly configured (with the
exception of allocated system memory), work fine.
One plan is to make a backup of this server and run yum update. Plan B
is to try reducing the allocated system memory down from 12GB to the
more common 8GB - counterintuitive, no?
