Java taking too much server resources.
I recently installed tomcat via cPanel for a client. Java is taking up too many resources and i need to periodically kill all its processes or it ends up overloading the server at which point the server stops responding.
Anyone have any idea why this would be happemning ?
Here's a copy paste of my current TOP printout.

I have seen java go as high as 13.7% memory usage per process.
If i launch Tomcat via cPanel then instead of java the process name is jsvc and that too behaves exactly the same, running a number of different processes all taking up veryu high ammount of memory.
Any help is appreciated.
