|Component:||Microsoft Exchange Message Transfer Agent|
|Message:||An MTA database server error was encountered while unlocking a queue. Called from <directory name>. Procedure <name>. Database error code: <error code>. Queue: <name>. [<value> <value> <value> <value>] (14)|
The message transfer agent (MTA) encountered an internal processing error while processing a message or report object. This indicates a logic error or database integrity failure. The Microsoft Exchange Server disk may be full or a disk error may have occurred. The message transfer agent (MTA) service will stop if the disk is full. The MTA DAT files may be corrupt.
When an installation has several gateways and connectors configured, additional resources may be required. You can modify the registry to avoid this resource shortage.
If the Microsoft Exchange Server disk is full, delete any unnecessary files. If you suspect a disk error, run Chkdsk. Verify that the \Exchsrvr\Mtadata directory exists. 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.
