| Description | A fatal internal MTA error occurred. Contact Microsoft Technical Support. Thread is adding null buffer to queue. ID = <id> [<value> <value> <value> <value>] (16) |
| Event Information | The message transfer agent (MTA) either encountered an invalid object and cannot process it, or it has database corruption. 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. |
