For a couple of weeks now, we&#039;ve been plaged by a problem of w3wp.exe spiking the cpu usage to 100% for several seconds. This happens very frequently, and causes "page cannot be displayed" issues. I&#039;ve been watching, and we really aren&#039;t getting that many people in the system all at once. Maybe as many as 10 or 15 at one time. I&#039;ve been able to use iisapp to give me the following information: PID 2924, DefaultAppPool. I really don&#039;t know what that tells me. I was hoping that I would be able to find out which of our web sites (and dare I say, the specific file that is being access, if that is the issue) on this server was causing the problem, and take care of the issue, but "PID 2924, DefaultAppPool" doesn&#039;t tell me anything.<BR><BR>We&#039;ve got about 10 web sites running on this web server. Only one of them is really active. Have I set IIS Up Wrong? Does anyone have any ideas how I can track this down and resolve the problem?<BR><BR>Thanks,<BR>Jesse
