"Geocode was not successful for the following reason: OVER_QUERY_LIMIT"

Greetings,

I received the following notice above when I accessed the list of events. I had 'x' amount of events listed. The note appeared once I added one more event after 'x.' I deleted the event and re-accessed the events. The notice goes away. I re-created the event, the notice appears.

What is that? Is there a limit? Are events or bookings restricted in some way that I don't know of? Actually here is the link. Click the menu item EVENTS to have a look.
