Answer 1

IIS comes with a feature called Rapid-Fail Protection. By default an App Pool is configured to become disabled if a worker in the pool crashes 5 times within a 5 minute span.

The thresholds of this setting are able to be modified by right clicking on the App Pool going to Advanced Settings and modifying the 'Rapid-Fail Protection' properties. However, this event indicates that there is likely a serious issue in your application that needs to be resolved.
