You mean these params: "-XX:PermSize=768m -XX:MaxPermSize=1000m" ?
Well, my app is under intensive development now and I need to reload
context quite often.
I know it's a big numbers, but without that after few reloads I'm
getting a memory exception.

Yes, that is a good reason, consider using a current version of Tomcat
(6.0.32 or 7.0.12). They will give you hints where memory leaks are, so
you can fix them.
