| Event Information | "According to Microsoft: CAUSE: The Host Account Cache database uses a log shipping mechanism for database synchronization. When the master Host Account Cache database is updated, the log shipping mechanism sends a message to the backup Host Account Cache databases. The message indicates that an update is available.
