How can I trigger the garbage collection?

Here is the thing, the gc should trigger when it reaches 75% of the heap,
then elasticsearch frees the old generation. Every now and then, a node in
our cluster miss this step, and stop calling the garbage collection, even
when this threshold is met. When this happens, it is a matter of time that
the node crashes. We can monitor the jvm, and restart tje npde, since we
prefer a 'controlled' restart than nasty calls in the middle of the night.

Quetion: can I force the jvm to do a gc round?


es: 1.3.2
jvm: oracle 1.7
