On the SharePoint home page the K2 Worklist web part does not load when the K2 database server is offline. This occurs when the K2 Worklist web part does not “timeout” when it can’t reach the K2 database. This makes the SharePoint sites unusable when there is an issue with the K2 databases, making the K2 databases critical for usability of SharePoint as a whole.
