The error code 0xfffffd9a translates to JET_errCheckpointDepthTooDeep



This issue occurs if the storage group that is related to the information store contains more than 1008 uncommitted Extensible Storage Engine (ESE) transaction log files. Each ESE storage group has a hard-coded limit of 1024 uncommitted ESE transaction log files. When the number of uncommitted ESE transaction log files in an ESE storage group reaches 1008, Exchange Server 2003 or Exchange 2000 Server starts to dismount all the information stores in the storage group. Additionally, the event ID 1159 message is logged in the Application log this is by design.
