We are running Sitefinity 7.3.5610.0. Within the last week we are getting some odd behavior where all the links on the site suddenly break. If you click on a link you get 404 errors. When you inspect the links you get the "id" of the link instead of the correct link. It appears Sitefinity is having a hard time resolving the link. For example the link resolves as: www.example.com/[f669d9a7-009d-4d83-ddaa-000000000002]0db1f99d-cc8b-6082-baa9-ff0000122be3. The ID for the page is in the url and not the correct link to the page.
The site will then suddenly fix itself after about 10 minutes or so and ALL the links will work again. I cannot determine a cause. SQL Server is fine...Web server seems fine. Any clues?
