ASP.NET process eats all CPU time

[Casper Hornstrup]

On a Windows 2000 Server/IIS 5.0 with ASP.NET 1.1 in a production
environment, I'm experiencing that the ASP.NET process is eating all CPU
time, making the websites very slow. How can I debug this? It is probably
just one of the websites that causes a problem. How can I find out which?

Thanks,
Casper

Hi Casper,

From your description, you deploy a asp.net web application on a w2k server
machine and currently you found the web application is suffering 100% cpu
utilization problem, yes?

Based on my experience, there're many things may cause such problem.
1. There is a kb article on the the frequent string manipulation will cause
the problem:

http://support.microsoft.com/?id=307340

2. Also, some times the problem may be caused by the code logic in the
asp.net web application. Such as deadlock.

3. And have you used any third-party component or other components, they
also will cause the problem sometimes.

If the general check can't help, I think we need to request some in depth
troubleshooting such as dump analysis. Also, you can have a search in the
newsgroup for some former threads which may also provide some clues. Thanks.
