Event ID - 3128

Event Id3128
Description An MTA database server error was encountered. [%1%2%3%4] (14).
Event InformationAccording to Microsoft:

When you analyze the application log and look at the details of all these Event IDs, it becomes obvious that "object at fault" in each Event ID is pointing to the same message object, a corrupted message. In the Event IDs above, this is the Db000034.dat file, which is located in the MTA database folder.
Even though the above Event IDs state the "Object does not exist," it may exist in the Mtadata folder. If the corrupted file (Db000034.dat in this example) still exists in the Mtadata folder:
1. Stop the MTA service.
2. Rename or remove this file from the Mtadata folder.
3. Run the Mtacheck utility twice.
4. Restart the MTA.
If the message file does not exist in the Mtadata folder:
1. Stop the MTA.
2. Run Mtacheck twice.
3. If Mtacheck registers that the MTA is clean, restart the MTA.
Explanation :
A message transfer agent (MTA) database server error was encountered. Specifically, a message that was expected to be in the queue was not found. 
User Action :
First, stop the MTA and run an MTACHECK command. Attempt to start the MTA.
If that fails, perform an MTAWIPE of the MTADATA directory: 
Make a backup copy of the Db*.dat files in the Exchsrvr\Mtadata folder on your hard disk.
NOTE: Do not skip this step. If the MTA does not start after you reset the MTA database files, restore the backup copies of the Db*.dat files to work around the problem. 
Copy all of the files in the Setup\I386\Bootenv folder on the Microsoft Exchange Server CD-ROM to the Exchsrvr\Mtadata folder on your hard disk.
NOTE: There should be 40 files that are copied to this directory. 
Select YES to overwrite the existing files. 
Remove the read-only attribute from the files that you copied from the CD-ROM to your hard disk. No files in the Exchsrvr\Mtadata folder on your hard disk should have the read-on
