Why would IIS7, on a Server 2008 box, spawn multiple w3wp processes which end up consuming hundreds of megabytes of memory when the only apps running on it are the ones Exchange installs to provide remote access capability and there are only two users who do remote access? I should also point out that only one of those users does a significant amount of remote access (this is a development environment). This doesn't seem right. But I'm not sure how to resolve the issue. - Mark

It would be better if you try posting here and see if you can get help IIS7 - Performance http://forums.iis.net/1050.aspx Vinod |CCNA|MCSE 2003 +Messaging|MCTS|ITIL V3|

I'll do that, but I'm pretty sure Exchange has something to do with the issue, since the only application running on the server right now is Exchange 2007 SP2- Mark

Hi Mark,If you use the Outlook Anywhere feature create a seperate application pool for it. This is a recommendation by Microsoft which you can find on the following site:http://technet.microsoft.com/en-us/library/cc540453.aspxRegards,Johanblog: www.johanveldhuis.nl

Johan,Thanks for the tip, I've moved OA to its own application pool. I'll see if that helps.- Mark

Mark,And has this fixed your issue ?Regards,Johanblog: www.johanveldhuis.nl

No, unfortunately it has not. Multiple instances are still appearing, their memory usage is amazingly high considering there's only one application and one user utilizing them. And I'm still getting random crashes (I didn't mention that last point in my first post).- Mark

Mark, Hmm that's bad news, are there any event logger in THE event log? Regards Johanblog: www.johanveldhuis.nl

Yes, it is :).I've opened a case with Microsoft support, and we're currently trying to figure out just what in the heck is going on. Unfortunately, there are no events logged and no warning messages that imply an impending shutdown. What's even more interesting is that the system does not die to blue screen -- it goes all the way to power off.- Mark

Mark,Keep me informed I am very curious what is causing the issue.Regards,Johanblog: www.johanveldhuis.nl
