Your -Xmx, your MAX heap will not grow. Your CURRENT heap may grow.

For example...

You start with a -Xmx of 1g.

App starts with a heap of 256m. It may slowly grow (depending on load etc.) to 1g, but it should never pass 1g. If it needs more than 1g of memory it will crash.

No

OS is not the problem, probably is your app as BalusC suggested
