This typically occurs in databases that first launch the integration or recently included a new role to sync from the "ON" products into Raiser's Edge. A large number of pending updates will impact the performance of Connect RE. Users are recommended to dedicate time to match, link, and process the bulk of their updates as soon as possible. Depending on the amount of data that syncs through the integration, users should regularly be dedicating time to working in the integration to avoid a bottleneck of updates to be processed.
