I started receiving the following my mysql error log today (once every 30 seconds): [Note] Unknown database 'sunl' yes, those are not normal characters (backspace and Start of Heading) The only way I can find to stop the error is to create a database with that exact name. If I try to drop the database after creating it, the errors start back up. This was not a database that was ever created on this server. This server is acting as a replication slave, so I check the master and there is a similar, but different named database causing the same issue on that server. Any suggestion would be appreciated.
Check your code because somewhere that database is being used. If you can't find the database name anywhere in the codebase, it may be in the encrypted PHP file behind a hack. Search for base64 encoding functions. What is the language of your front end?
