    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.

    Thanks. Pardon me I an noob can you please tell what plugin should i use to optimize my database. As I am using Cloud Fare and WP Super Cache. Does WP Super Cache Plugin optimize the Database? please Suggest.

    WP Super Cache plugin does not optimise database
