Hey all,
The error was:
2010-07-05 11:19:05,817 ERROR mojoPortal.Web.AppKeepAliveTask - System.Net.WebException: The operation has timed out
at System.Net.HttpWebRequest.GetResponse()
at mojoPortal.Web.AppKeepAliveTask.DoKeepAlive()
It appears to have been caused by the use of the AppKeepAliveUrl web.config setting when the Application Pool was in 'Integrated Pipeline' mode. I switched the site to use an 'Integrated Pipeline' app pool and the error stopped.
Thanks,
Joe D.
