For some reason, IIS process (W2WP.EXE) is consuming 95-99% CPU at at all times. I'm trying to determine what is going on but I can't see anything obvious. Last time we saw this issue it was because the website was trying to log data to a log file in an infinate loop but I dont see anythig like that now. I have run procmon for 5 minutes but I don't really see anything indicating what the issue might be or what it is doing. Of course, I'm no expert.

How can I determine what a process is doing that is causing it use consume so much CPU?

Can you isolate which web application is causing the problem by turning each off in turn.

If the application is asp.net, you could attach it to a debugger. Or use Jetbrains Profiler.

  • There is only one site running, but we cant attach a debugger because it's deployed in release mode. I'll try the profiler and see what i get Oct 5, 2011 at 22:44
  • have you tried recycling the app pool? does the event viewer give any indication? are you using any logging?

    JetBrains was a big failure, at best it crashed the process. I used ProcExplorer to determine what the issue was and it pointed to something happeneing with .NET so I went ahead and used RedGate Profiler to see wtf was going on and now I'm trying to figure out how to fix it. thanks.
