Issue: After restarting the server, in just a few minutes, the number of w3wp processes rose to more than 100, which is an unhealthy state to run out of CPU and memory, eventually causing the server to fail.
Through the anti-virus at the same time to close the relevant sites, the number of processes dropped to 60 or so, tending to normal, when the server restarted, the following situation occurs:
1. The Web site prompts "The specified module cannot be found";
2. HTTP 500-Internal server error;
3. http 401 error;
4. http 404 error;
For the above error, no matter how the configuration can not run, there is only one possibility, IIS itself has a problem, by reinstalling IIS, that is, all issues resolved.
