Just spotted the following posting from Paul DuBois on the internals mailing list:

I'm engaged in a project (WL#3403) to compile information that will provide better information about our errors and error messages:

• What an error means
• Likely causes of the error
• How to rectify or work around the error

The general idea is to provide our users something more than a list of error codes and the messages from errmsg.txt, such as the manual currently includes here:

http://dev.mysql.com/doc/refman/5.1/en/error-messages-server.html
http://dev.mysql.com/doc/refman/5.1/en/error-messages-client.html

To that end, and to give lucky YOU a chance to participate in this exciting (!!) project, I'd like to solicit your knowledge on a case by base basis. To that end, I'll post individual messages for different errors, indicating what I know about them and asking for additional comments. I hope in this way to take advantage of the knowledge that different developers have about errors that pertain to their particular areas of expertise.

I think this an excellent initiative, as some of the error messages are quite confusing/misleading!

And without further ado, Paul already started with his first post: Error of the day: ER_HASHCHK - which according to Kostja is not actually used...
