Event ID: 2048
Source: MSExchangeMTA
Version: 6.5.0000.0
Message: An internal MTA error occurred. The thread list is empty. The list type is name. [valuevaluevaluevalue] (12)
   
Explanation
The message transfer agent (MTA) database may be corrupted.
   
User Action
Stop and restart the MTA service. If the error persists, run the Mtacheck.exe utility. Stop the MTA service, open a command prompt, and type Mtacheck/v /f c:\mta.txt.

If Mtacheck removes objects from a database queue, it places each damaged object in a Db*.dat file in \Exchsrvr\Mtadata\Mtacheck.out. Check your drives and verify that core *.dat files are in the \Exchsrvr\Mtadata directories. The \Exchsrvr\Mtadata directory with *.dat files may be on more than one drive. Contact Microsoft Product Support Services for assistance.
