I use an INSERT INTO & DELETE FROM combination in a PHP script to take data out of an operational MySQL table and put into into an archive table.

The archive table has gotten too big. Even though no day-to-day operations are performed on it, mysqldump chokes when we back up (error 2013):

Error 2013: Lost connection to MySQL server during query when dumping table 'some_table' at row: 1915554

What can I do? Should my PHP script move it to another DB (how?)? Is it okay to keep the large table in the operational db?–in that case, how do I get around the mysqldump issue?

Thanks!

    Are you by chance dumping using memory buffering and running out of swap and physical RAM? If so, you can try dumping row by row instead.

    Try adding –quick to your mysqldump statement.

    According to the documentation, you should combine –single-transaction with –quick.
