Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

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?

TomTom posted what the answer is more than likely is. I would follow that path of troublesooting. –  Techie Joe Oct 29 '12 at 15:30

1) is there a way to throttle how much memory is consumed by the w3wp process before I can force it to restart

No, and it makes no sense because - the apps live in their own processes.

2) any ideas what could have caused this to start happening?

Yes. Bad code. That it as good as it gets without attaching a Debugger. THAT SIAD: 460mbis not exactly a lot of Memory. Can be some bad Caching.

ok it turns out it might not be a memory issue. I just did an iisreset an cleared up a ton of memory but still seeing the same issue where IIS does not serve pages on some initial page requests. I have to refresh the page several times to get it to load. I'm pulling my hair out here. I have no idea what's causing this or why it started or worst of all...how to fix it. Here is the other thread I started yesterday about this issue: serverfault.com/questions/442777/… –  Charles Oct 27 '12 at 19:38
