Why is Jenkins using so much memory?

I just started htop in my VPS and filtered to Jenkins to see if this was what was taking so much memory. Holy crap?!

I only have two build executors and only ran the service once (on machine bootup), so...why is this?

I only have 1 gig of ram on this VPS and I need to run Apache, Nexus, and Jenkins. Why is Jenkins being such a hog of resources like this? How can I counter it?

Also, if it helps, I am polling SCM every 30 minutes for changes in Jenkins, but that couldn't be responsible... could it?

You are using ant target build-parallel?

Try changing to the target build without parallelism
