Hi All,

I had post it to a wrong place as no one can answer it, so i post it again here , Admin: please delete this post

 I just fresh installed DNN 6.1.2 with Default Application Pool - DefaultAppPool  (Identity = Network Service,  Add 'Network Service' to DNN Database as DB Owner, and Full permission on DNN installation folder)

however once I log in as host or admin, modify content  of  a html/text module - wait for 20 ~ 30 minutes, my windows server 2008 (not R2) always reports following warning:
A process serving application pool 'DefaultAppPool' exceeded time limits during shut down. The process id was '2960'. - Event ID 5013

after 1 minute of this event log (this is normal information log):
A worker process with process id of '2960' serving application pool 'DefaultAppPool' was shutdown due to inactivity.  Application Pool timeout configuration was set to 20 minutes.  A new worker process will be started when needed. - Event ID 5083

Then I disabled all jobs in the scheduler, and tried again, same thing happened

But I download the DNN version 5 (released last november), installed it on the same server, this warning did not happen, so I believe this issue is from DNN 6, not my server

Tried to debug to see which resource causing this issue, but no luck

Could some one verify this warning is a "Feature" of DNN 6? or a bug , or something I can ignore???
or How can I fix this?

 My server is Xeon 3.06g dual core, 3G memory

Thanks in advance

This looks quite normal to me.  ASP.NET has a default session timeout of 20 minutes.  So it shuts the application pool down. (Nothing to do with DNN)

So when DNN reports it now, it's a nice new feature which helps you to understand why sometimes your site is getting slow.  That’s why the page keepalive.aspx is there; normally you would have a service that accesses your page every 5 minutes, so preventing the session timeout to kill your application pool.   (Google for “DNN Keep Alive”)

If you want I can add your website to my keep alive service

Best regards
Olivier

 Thanks Oliver,

One thing I don't understand is DNN v5 does not have this warning event logs, 
Windows server 2008 reports lots of this warnings, which worries me

Most likely this is due to the fact that DNN5 did not capture this event (it’s not actually an error).

I did not notice this event on my websites, and I often trigger this event manually and never saw it in the event log. (DNN4)  So I do not see any reason to worry, just to be happy for the new feature.
