IIS 7.0 system log error and how to handle this.

One error in my system log.  WAS 5189

The Windows Process Activation Service failed to generate an application pool config file for application pool 'DefaultAppPool'. The error type is '7'. To resolve this issue, please ensure that the applicationhost.config file is correct and recommit the last configuration changes made. The data field contains the error number.

Last change to IIS was to change the recycle time from 1740 minutes to 0.  I used appcmd list config command to check the application host file and it is fine with no errors.  

It says if there are no errors in the XML code for applicationhost.config file then do nothing.

This is the first time I have seen this and it only came up one time during a 7 day period.  May 31.

How to handle this error or just ignore it?

I would try re-doing the change using an elevated command prompt and see if the error is thrown again.

Also, can you post the complete XML formatted event message from the event log?

I made the change in the interface using IIS manager.  I am not sure how to make that change using a command prompt.  Setting the recycle rate to 0 from there.

Here is the xml version.

Since the appcmd list config returned no errors, there is no concern.
