Hi there Did you resolve this? We’ve just had a backup that ran for years start failing with this error about a week ago. We’re running 5.7 and 2.4.28 in Docker. I thought it might be something to do with table size, and we had a huge table that was a temporary backup that I got rid of. It’s worked once since I got rid of the big table but it’s gone back to failing again Any clues gratefully received Thank you --- _[View the full topic](https://forums.percona.com/t/help-diagnosing-error-2013-hy000-lost-connection-to-mysql-server-during-query/6923)._
