There should also be a username mentioned in the error, the user who triggered the error. Please contact them and ask them to tell you how they managed it - I'm not able to replicate it locally.

If it happened 100% of the time when someone attempted to send invites, your inbox would probably be flooded, so something special most likely occurred.
