Week 16 of a 52 series on what every web administrators needs to know to be successful in this space. This week covers the w3wp.exe worker process and the theory behind recycling app pools, forcedly killing the w3wp.exe process and what's safe in a production environment.

Microsoft’s Internet Information Services (IIS) web platform is extremely robust, and one of the neat features is overlapping application pools.

In today’s video I cover the theory behind overlapping app pools, forcibly killing the w3wp.exe worker process and on-demand starting of app pools. This is helpful in knowing the impact of recycling an application pool, and what measures you can take when troubleshooting high CPU, high memory or other issues in your IIS environment.

This is week 16 of a 52 week series on various web administration related tasks.
