Filed a bug, reproduced it on 042stab053.3 and also today on 042stab053.5.
Noticed few more different things - when I set privvmpages to 12G:16G, I
can't start java (hornetq) with -Xmx set to ~7G, and UBC increases failure
count on privvmpages, program fails to start with:
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
(so there is something here, that accounting at least notices).
( when I reduce -Xmx to ~6G, hornetq starts, and then I get 'out of memory'
errors on console/HN ).
Also, it seems that limiting heap with -Xmx to ~512M makes it possible to
run one or two instances with hornetq without ill-effects.
regards, Eyck
