Driekes Boutier on "Exploding table in MySQL"

Hi there,

We are using an multisite set-up with about 400 websites in it. There is one table in the MySQL database that is exploding. How is this possible?

On this website WooCommerce is active, and within the table i see many transients etc.

How to fix this?

Best regards,
