Why does Tomcat 7 Memory usage looks like saw? (picture)

Why does Tomcat 7 Memory usage looks like saw? Souldn't it be more stable? Has it got something to do with the GC? And if yes, does it mean there is a "leak" that is present? By the way this server is a test server with nothing on it.

Thanks!

It's just the way the Java garbage collector works. It lets memory accumulate until it hits a certain threshold, then it runs the garbage collector and frees up what it can. So it's not that Tomcat's actually using more memory, just that Java hasn't bothered to free it up yet.

saw pattern is very normal.

even if app is doing nothing, there are background tasks that create garbages.
