This issue may occur if the following conditions are true:

• The log files and databases are shut down correctly. Therefore there is no crash to recover from.
  
  
• You rename or delete the Exx.chk checkpoint file.
  
  
• There are more than 1,008 log files between checkpoints to replay on the server.
  
  
• In a "roll-forward" recovery, one or more databases in the storage group are lost, but the log files remain intact on the server at the time of recovery. The "roll-forward" recovery operation is not completed successfully.
  
  

In this situation, the Microsoft Exchange Information Store service performs a soft recovery and replays all log files during startup. Because the log files and the database were shut down correctly, there is no recovery to perform. Because there is no checkpoint, Exchange processes all the logs until it reaches a record of a clean shutdown. Because there are more than 1,008 log files, Exchange reaches the limit of 1,008 log files before it can locate the record of a Clean Shutdown state.

Note:
The symptoms described may also occur if the conditions listed earlier are true, and you replay the log files by using the eseutil /r command. The eseutil /r command also performs a soft recovery on the mailbox store.

The error can also be identified as error JET_errCheckpointDepthTooDeep, -614. This error applies to Microsoft Exchange Server 2003 only.

To resolve this issue in Exchange Server 2003, apply the hotfix prescribed in Microsoft Knowledge Base article 836611, Information Store databases do not mount and you receive an "Operation terminated with error -614" error message when you start a computer that is running Exchange Server 2003.
