Tomcat 7 eating too much memory on Ubuntu

[Projeto Manager <pr...@gmail.com>]

Hello,

I have the following config:
Tomcat 7
Ubuntu 10.04.3 LTS
jdk-7u51-linux-i586.tar.gz

My web app does not have any users. It's just me. After about a week of
running, the java process is eating a lot of memory, and then the swap
demon eats all my processor time. Then I have to restart tomcat.

This is my memory status when things are still ok:
Mem:    509216k total,   416808k used,    92408k free,    20816k buffers
Swap:   262140k total,    20688k used,   241452k free,   201384k cached

How can investigate this problem further? Should I use Tomcat 6 instead? I
am a java beginner.

Use a profiler to find the memory leak(s) in your application.

No. Why would you think that was a good idea?
