I'm not sure I understand what you're saying here. How in the world are you supposed to load test a secure web application if this is the case? I don't see how testing a secure application can be so much more memory intensive for jmeter than a non-secure web application. I am using a dual-processor server with plenty of power to run jmeter. Is there nothing I can do to reduce the amount of memory the script is using so that jmeter won't crash?
Is it possible that something with the way my script is handling SSL could be the culprit? Elli > HTTPS is a tremendous CPU hog and will eat up plenty of RAM.
