That just indicates how much memory Java has got, it does not necessarily mean it is all being used. > What if I want to make a test of few hours, is there a guideline how to > configure the jmeter's java options. Not possible in general. Search the archives for some specific examples, but it depends so much on what the test contains. > Can you configure JMeter so that it'd free it's memory occasionally?

JMeter calls the garbage collector before starting a test. And the JVM of course will continue to garbage collect as a test runs. There are options for tuning the JVM gc, but that varies between JVMs - check the JVM documentation. I don't know whether Java ever returns memory to the OS once it has been given it.
