I have a server with applications in Aspnet running IIS 7.
Always worked normally. But since yesterday the CPU is always using 100% in the times with more access, causing unavailability in several sites and loss of performance.
I have tried to limit the size of the pool in memory and limit the processing of pools, I have already restarted the server and IIS several times, but it always comes back.
Does anyone have any ideas on what I can do?
It may be a problem in some applications , if an application misuses memory or other system resources, the effects usually appear in IIS.
To check if it is a problem in some applications you can use tools that will help you diagnose which Work Process / work process of which specific application is consuming the server's CPU and verify is a problem in a timely manner (problem with an X page, a loop, etc.).
To check the consumption per application:
1. Open IIS
2. Select the server / root
3. Click Worker Processes

This link has a few steps to help you diagnose and resolve these issues.
