Description:
Application pool 'apppool_name' is being automatically disabled due to a series of failures in the process(es) serving that application pool.
Well, your worker process is crashing way too many times than it should. The default value is 5 crashes in 5 minutes, and your pool will be disabled.
Now, as you can see... you shouldn't be trying to fix Rapid Fail protection. Concentrate more on how to fix the crash. This blog here, might help you.
