This is the problem I am facing.

I have a tomcat 7 server running on JDK 7 - Win2008 32 bit.

Exactly which versions? There are 23 of Tomcat to choose from.

I am monitoring all the memory areas. I am seeing the Survivor Space is
highly consumed almost all times. I have reduced the survivor ratio to 6.

Survivor spaces fill up if objects survive a collection in Eden. How big is

But unfortunately no improvements. I have changed the MaxPermSize as 256
from 64 (Not sure is this a right one).

It's not.

Can you please suggest me a correct option to increase the survivor space?

You are using the right option, but you are probably trying to change the
wrong thing.

What are you really trying to achieve?


Any help will be highly appreciated.

Here is my setting.

MaxPermSize increased to 256 recently.
