[Warning] Aborted connection 718646 to db

Hello Everyone!

I am seeing some errors in the MariaDB logs and wanted your input on the same. Following are the errors I see and I did some changes to the MariaDB configurations but the error doesn’t go away. Anyone can help me identify what this could be?
