Loads the pages only partially. While loading the page, the TooManyCallsException error appears in the error log. It does not impact all the pages. It only impacts the pages with too many includes.
While loading a page, TooManyCallsException is thrown because there are too many includes within the page. As too many includes cause performance issues, the OSGi configuration has limited the number of includes in the SlingMainServlet. If a page requires numerous includes, then increase the property value.
