question about Java and VIRT(ual) memory

[Bobby Bissett]

Hi,

I tried this question in another mailing list (I didn't know where it
belongs) and someone suggested I try here. If there's another list that
would be better suited, please let me know.

A customer is running a Java application of ours that runs with -Xmx128m --
there are no problems specifically with the heap. But the process is using
over 4 gig of VIRT(ual) memory according to 'top'. I didn't think that was
generally an issue, but they are running with "overcommit_memory=2" on this
linux system, and that 4 gig of memory is hurting things. Is there a jvm
parameter to help with this?

FWIW, they're running openjdk 1.8. They need to upgrade to something newer;
if there's any particular version that might help with the virtual memory
it would be nice to know.

Thank you,
Bobby Bissett
