| Description | An internal MTA error occurred. An attempt has been made to write <value> bytes of data to a buffer when only <value> bytes are allowed. Connection control block: <value>. Logical session number: <value>. [<value> <value> <value> <value>] (12) |
| Event Information | The message transfer agent (MTA) database may be corrupted. 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. |
