    Database is working fine. This error is coming due to traffic and it’s come sometime. So is there anything which this error should not come

    when database server is busy and cannot handle incoming traffic then you will get error. You can optimise database performance or upgrade database server.

    WP Super Cache plugin does not optimise database

    try https://www.ads-software.com/plugins/wp-optimize/
