Hi all. I have a 30GB innodb-only database in mysql-5.0.54. I have always done nightly backups with:
mysqldump --opt db_name > db_name.sql -p Recently this started failing with: Error 2013: Lost connection to MySQL server I have checked all tables for corruption - nothing found. Also as far as I can tell there are no issues with clients using the database. There have been no crashes since I did a full restore. So I assume we can rule out corruption. I have searched around for the error message, and found people discussing the max_allowed_packet option. I've tried increasing the server's max_allowed_packet to many different values. Currently it's at 128M, which is *way* over the default. I have also used the --max_allowed_packet option simultaneously with mysqldump. And lastly, I have been restarting the server after each my.cnf change. The data was inserted via the 'dbmail' application ( http://www.dbmail.org ), while the server was set up with the default max_allowed_packet size. DBMail breaks up message into chunks, and stores these chunks in individual records. I'm not sure what the default size of these chunks is, but I belive it's a reasonable value anyway. What next? I *must* get regular backups working again ... Dan -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=arch...@jab.org
