Hi All.,

While taking mysqldump I am getting the below error.

Can we add any options in ‘mysqldump’ command to get rid of this.

Are you running an ALTER TABLE on ts\_chain at the time when mysqldump was in progress?

I ran into this issue once. Can you run check table against that table and share the output?
