I seem to be getting a problem where my rails application seems to be  
leaking memory when I load a page. It starts off at about 737mb free.  
After  
I load my page it comes to about 603 mb free. When I restart the thin  
server  
the memory is restored, but thin does complain that it is waiting for a  
process to finish before killing the service and starting it.

Any ideas how I can go about finding where the leak is and fix it?

thanks

Check for bad database queries that take a long time to execute and  
load more junk than you need.
