Issue Summary: On Tue, Jan 21, a subset of customers experienced sub-optimal performance with Resource Booker, including slow response times and errors loading admin functions. Root Cause: The system degradation was caused by Resource Booker overloading the system with large volume of data when it searched for pending approvals and found none. This was caused by a bug that was introduced into the software that surfaced in the production environment. Corrective Actions: Temporarily optimised the search services to handle more requests. Preventive Measures: Updated Resource booker to only search for events when necessary and only a subset of the data.
