J2EE Engine memory consumption (Usage)

Dear experts,

We have J2EE Engine (a Jawa stack). When I run routine monitoring via the browser and read the memory consumption I am meet with a chart that show a sawtooth like graph. Every hour from 19:00 to 02:00 the memory consumption will rise with approx. 200 MB after 7 hours all of a sudden the memory consumption drops down to normal idel levvel and start over again. I can inform that at the time there are no user on the system.

My question is what are the J2EE doing? since there is no user activity.Are the J2EE engine running some system applications? is it filling up the log files and then empty(storing) them.

I hope some of the experts can answer.

I just want to undertand what's going on, on the system. If there is some documentation/white paper on how to interpret/read the J2EE monitor I will great full if you drop the information or link here.
