Hello--

We recently upgraded our Umbraco installation from 6.1.6 to 6.2.2. I have noticed since the upgrade, our log files have been filled with thousands of the following entries:

Logger: Umbraco.Web.Scheduling.ScheduledPublishing

[Thread 173] An error occurred with the scheduled publishing

System.Net.WebException: The operation has timed out

at System.Net.WebClient.UploadDataInternal(Uri address, String method, Byte[] data, WebRequest& request)

at System.Net.WebClient.UploadString(Uri address, String method, String data)

at Umbraco.Web.Scheduling.ScheduledPublishing.Start(ApplicationContext appContext)

and

Logger: Umbraco.Web.Scheduling.KeepAlive

[Thread 174] Error in ping

System.Net.WebException: The operation has timed out

at System.Net.WebClient.DownloadDataInternal(Uri address, WebRequest& request)

at System.Net.WebClient.DownloadString(Uri address)

at Umbraco.Web.Scheduling.KeepAlive.Start(Object sender)

These errors don't appear to affect our Umbraco installation, but I'm curious what these errors are about. What is causing them? Is there something I'm not aware about going wrong? Is there something I forgot to configure after the upgrade?

It's just a single, non-load-balanced installation. There are rewrite rules to: force https, force "www.", and force a trailing slash, but I don't think it would affect the "UploadDataInternal" function Umbraco is using.

Any thoughts would be appreciated.

Thanks,
