Looking at the log file on our CD server, I noticed that there are loads of warnings getting logged every millisecond for a document not found redirect for the home page of the scheduler website:

9376 09:20:17 WARN Request is redirected to document not found page. Requested url: /, User: sitecore\Anonymous, Website: scheduler

The scheduler is indeed a node of the sites section (this is a multi-site solution), third from the bottom and after all the actual public facing sites but has nothing more than name, domain and enable tracking set to false.

<site name="scheduler" enableTracking="false" domain="sitecore"/>

The only way I can even imagine the site getting accessed is by specifying via query string sc_site=scheduler but that still doesn't explain the frequency that it is getting logged.

  • Do you have any agents being ran on your CD Server?

  • Good question. Not that I am aware of. But I'll check with our infrastructure team.

One thing to be aware of, is that in Sitecore's Site Provider, order of sites is incredibly important. If for some reason, your order has become unordered.. and the scheduler site shows up in the list BEFORE other site definitions, then Sitecore will land on the scheduler site as the Site for the current Context.

Sitecore's Site Provider processes sites using a Most Specific to Least Specific case. Because the scheduler site has the least amount of requirements, if the sites are out of order, it will chose that site.

This is why scheduler, publisher, and system sites show up AFTER the website site in a default config.

Things To Check

  • Check your ShowConfig.aspx to see how sites are ordered (if using config patching for Site definition.
  • If using any kind of Multi-site manager or dynamic site module, ensure that your site definitions are putting your site before scheduler.
  • Check to ensure that all site definitions exist. If there isn't a catch all site like website that has a empty hostname attribute, then I could also see how a request gets to the scheduler site.
  • Also check to see if any rogue Scheduler Agents are being processed on the CD. (Likely not, but good to check)

  • Great answer, Pete! Can you elaborate a little on what you mean by "the scheduler site has the least amount of requirements"? Are you referring to the number of attributes, or something else?

  • Yeah sure.. I'll elaborate in the answer, but I gotta go back to work first.:) Give me a few to get to it.

  • Pete - thank you for the thorough answer! I did check site via the ShowConfig.aspx and everything is ordered correctly. I did notice that the website site node has a hostName attribute, so I will try removing so it can be a catch-all to see if it helps. If so I will mark this as the correct answer.
