IIS Worker process recycles soonner than the regular time interval set (Both 6.0 and 7.0)

Question

Hi All,

We've configured our application pool to recycle at a regular time interval of 180 minutes. But the worker processes are getting recycled every 60 minutes.

Is this a known issue, or do we need to configure something else?

Thanks

As stated in http://stackoverflow.com/questions/302110/what-causes-an-application-pool-in-iis-to-recycle:

You might want to turn on full AppPool Recycle Event logs:

cscript adsutil.vbs Set w3svc/AppPools/DefaultAppPool/LogEventOnRecycle 255

You also might want to take a look at this Scott Guthrie blog article: [http://weblogs.asp.net/scottgu/archive/2005/12/14/433194.aspx%5D%5B1%5D that shows how to write code in Global.ASAX to log the actual cause of an Application.End event.
