The agents database has become corrupt.

Replacing the agents MDB File with one from anotherr agent will fix the issue. It does not matter which agent you use.

to Do this:

1. Stop the target agent.
2. On the Agent host, Browse to \\servername\QMMEX$servername$ where servername is the name of the machine.
3. Open the Agent Folder, and you will see the config.mdb
4. Rename this config.mdb to .old or delete entirely
5. Copy the config.mdb from another agent that is working (and is currently stopped),
6. Paste the new config.mdb to the failed agents folder
7. Re-apply agent configuration
8. Start the MTA.
