Hi, I have tried using: mysqlcheck -u username -p database And the result: ... intranet.company_sector OK intranet.comunicat OK mysqlcheck: Got error: 2013: Lost connection to MySQL server during query when executing 'CHECK TABLE ... ' I have tried for more times, but with no luck. At this point it stops and gives that error. The system frozen and I needed to force restart it, and after this, I think something bad happened to my database. Some of the database tables (MyISAM) have more than 3 million records and new records are inserted by a few programs, and in the meantime more users query them. Is this too much for MySQL? Thank you.
