Rails application hosted on slice eating up memory like giant

I am working on a normal CRUD application using rails 3.0.9

I have deployed the application on the Slicehost (RAM 512 MB). But when i access the application within 5 mins it takes up all the memory & application crashes.

Can anybody will hel开发者_开发百科p me out here?

Run top, then hit 'shift+m' to see which proc is eating up the RAM.

It may not be the rails app, but rather MySQL or Apache launching too many processes .. too many mogrels if deployed using mongrels.
