We upgraded from 7.0.6 to 7.4.2.  The event log in 7.0.6 did not show any issues, but after upgrading to 7.4.2, we started getting a WEBSERVER_UPDATED  Logtypekey followed by a Application start.  They are happening about 2x minute and bogging the site down so it is pretty much unusable.

 We researched possible issues and addressed the low hanging fruit (verified only 1 entry in the webservers table, turned off all scheduled events, removing unused extensions, etc.) with no luck.  We decided to do a clean install of 7.4.2 on another box and compare various aspects of the webconfigs and databases to see if we were missing something.  After the new install of 7.4.2, we found the same webserver_updated and application_started issues in the event log on the new install.  To see if this issue might have been addressed in the upgrade, we did a new install of 8 and found the same issues.

While there are lots of causes for the application restarts, each restart immediately follows the webserver updated message, so we are hoping to identify what is causing the webserver updated log entry and work from there.  We have been running DNN for years and have never seen a webserver_updated message in the log file before.  An example of the log entry is below

 <LogProperties>
  <LogProperty>
    <PropertyName>Server Updated</PropertyName>
    <PropertyValue>xservernamex</PropertyValue>
  </LogProperty>
  <LogProperty>
    <PropertyName>IISAppName</PropertyName>
    <PropertyValue>/LM/W3SVC/7/ROOT</PropertyValue>
  </LogProperty>
  <LogProperty>
    <PropertyName>Last Activity Date</PropertyName>
    <PropertyValue>8/11/2016 5:33:37 PM</PropertyValue>
  </LogProperty>
</LogProperties>

 

Any help would be greatly appreciated.

Yes, only one IIS website is accessing the database.  The site has its own app pool and there is only one work process assigned to the app pool (not webgartens no web farms).  The same situation for the two new installs of 7.4.2 and 8. 

We did not change IIS settings when we upgraded from 7.0.6 to 7.4.2 since we did not have any issues in 7.0.6.  Do the newer versions of DNN potentially require different IIS settings?

Hi!
I have the same problem and the problem seems to be the same as this thread below, I get rid of all WEBSERVER_UPDATED and APPLICATION_STARTED in my logfiles, and the app-pool is no longer craching.
