As per my experience memory leakage will avoid application coding level not by setting up the min and max memories.

It may help not sure. There are multiple scenarios for this.

This http://wiki.apache.org/tomcat/MemoryLeakProtection may help. Do you already have an issue or jsut trying to avoid it in the future?

Memory doesn't "just leak". It takes a program bug to cause memory leaks. No amount of VM configuration tweaking will change that. To avoid memory leaks, don't hack and slash the fastest-cheapest code you can. Take the time and effort to do the job professionally.

Tomcat 6 does have its own way of "leaking memory", which is the infamous PermGenSpace problem. If you repeatedly deploy a webapp in Tomcat without restarting it, some of the old webapp's static resources are not freed up by Tomcat and eventually you will run out of PermGen memory, which is a distinct memory pool from the primary heap/stack space. As far as I'm concerned that one is a deficiency in Tomcat, but it's something that can be managed by restarting Tomcat when re-deploying, unlike application-bug memory leaks which can happen with little or no warning.
