If function getPagePath is used in URL Pattern it could lead to lock for a SitePlan after a Refresh.
This usually happens when at the time of the Refresh other operations are performed, like moving the Pages inside the SitePlan, or saving a page after Edit.
The Refresh of the SitePlan will keep loading, it will not complete.
The lock will eventually lead to Stuck threads and the server will go into Warning State and it will need to be restarted.
