IIS7 on Server 2008

App Pool - .NET fx 4.0, Integrated mode, Idle Time-out = 0, is set to recycle once per day at 10 am. Maximum Worker Processes = 1.
At the scheduled time the app pool is recycled twice, both times with Event ID 5076 recorded in the event log. The app pool has 2 different process ids.  ie ...
at 09:59:58
A worker process with process id of '9076' serving application pool 'WBOffice' has requested a recycle because it reached its scheduled recycle time.

and at 10:00:00
A worker process with process id of '12088' serving application pool 'WBOffice' has requested a recycle because it reached its scheduled recycle time.

Anyone know why is this?

Hi Judith_,

To troublehsoot the EventId 5076, have you check the steps in this article:

Check or configure application pool limits

A worker process requests a recycle when it reaches its configured limits for time, number of requests, or memory usage. An underlying issue may have caused the configured limit to be reached. You can check or configure the application pool limits by using IIS Manager.

To perform this procedure, you must have membership in Administrators, or you must have been delegated the appropriate authority.

To check or configure application pool limit settings by using IIS Manager:
1.Click Start, click Control Panel, and then click Administrative Tools.
2.Right-click Internet Information Services (IIS) Manager and select Run as administrator.
3.In the Connections pane on the left, expand the computer, then select the Application Pools folder underneath the computer name.
4.In Features View, select the application pool. In the Actions pane, select Advanced Settings.
5.Check or configure the settings for application pool limits under the appropriate section(s).
