Ruby using too much memory when using codekit for compass

Question

I am facing a problem when using Compass with codekit. Ruby starts eating almost all memory of the OS. In the screenshot below you can see that Ruby is using 2.26bg memory. This problem happens when I'm using Sublime with Codekit to compile Compass. Has someone gone through this problem?

EDIT: This is the info when I inspect this process

Are all your files you use for sprites what they say they are? Does the extension match the mime-type? Haven't you accidentally saved a JPEG with a PNG extension for example?

I had the same problem when I accidentally saved a PSD with the PNG extension. Running a $ file --mime-type * in my image directories revealed which file was causing this trouble and saving it properly fixed it for me.
