After a number of web applications have been created in the SharePoint 2010 farm, further attempts to create a new web application through Central Administration result in the following:
As more and more web applications are created, the time in which it takes to create a web application increases. As part of the creation process, IIS is reset and by default, the application pool allows 90 seconds for the connections to close off before forcibly shutting down. When the number of web applications grows above 10, 90 seconds is not enough time for the provisioning to finish.
As a result, the w3wp process is killed and the provisioning process is stopped prior to the timer jobs being created.
The solution to this is to allow the process a longer amount of time before it is forcibly shutdown.
