I have several web sites on my windows 2008 server that have been working flawlessly for over a year. Just a few days ago I ran into an issue where my server stopped serving up pages on some of these sites for no apparent reason. I dug into it a little more today and I see that some of my sites (they're all asp.net mvc 3.0 sites), are consuming over 460MB of memory. Like I said, this just started the other day after a very long period of time of no issues at all.

I have two questions: 1) is there a way to throttle how much memory is consumed by the w3wp process before I can force it to restart (restart the app pool for a particular site) so that it doesn't keep hogging all of the memory? 2) any ideas what could have caused this to start happening?
