Exchange Server Error 614
XADM: The Information Store Is Dismounted If the Backup
Process Stops Responding
The information in this article applies to:
Microsoft Exchange 2000
Server
SYMPTOMS
When you are finishing a backup on your Exchange 2000
computer, the log files are not committed to the public
or private information stores. During the backup, the
checkpoint file is still increased for each log file that
is filled. After the backup process completes, the logs
are committed to the information stores until they reach
the highest number recorded by the checkpoint file.
If the backup process stops responding, the checkpoint
file continues to increment for each log file that is
filled. The checkpoint file continues to increment until
it reaches a maximum value of 1088. In Exchange 2000 Server
Service Pack 2 (SP2) and earlier, this value is 256. After
the checkpoint file reaches the maximum value threshold,
the information store is dismounted. The following event
is generated when the store dismounts:
Event Type: Error
Event Source: ESE
Event Category: Logging/Recovery
Event ID: 471
Date: date
Time: time
User: N/A
Computer: Server Name
Description: Information Store (3420) Unable to rollback
operation #65678740 on database C:\EXCHSRVR\mdbdata\priv1.edb.
Error: -614. All future database updates will be rejected.

CAUSE
The information store dismounts to prevent the checkpoint
file from becoming too far ahead of the transaction logs.
This behavior can also be used to determine if there are
unresolved issues with your backup.
RESOLUTION
To mount stores that are affected by this behavior, first
determine the checkpoint value from the Exx.log file for
the storage group that is affected. To determine the checkpoint
value, use the Eseutil utility. After you have determined
the checkpoint value, move the committed logs to a backup
folder.
Move the Edb.chk file from the log file folder, and then
mount the stores. Exchange now plays through the remaining
uncommitted logs and permits the store to mount.
STATUS
This behavior is by design
