w3wp problems

Last Modified: 2012-08-13
Its a known issue that the w3wp process can spike processor usage every few minutes, are there any known solutions? googling only reveals a patch from microsoft that the server admin (i work applications on the client) won't install for unknown reasons. This server is running software that monitors anesthesia durring surgeries, so when 4 instances of w3wp all peg out at the same time and things stop responding on the client side, its a big deal.
Watch Question


Thats your IIS .. is it slowing the machine to a crawl?  

What version .net are you running?  I'd try recreating the application pool.

Try to make sure the application pool is in High Isolation, if you're using Windows 2000 Server.
