Read ECONNRESET after a few minutes idle

[lijyze]

It happens every first time my app interactive with database after a few minutes idle.
I downgrade mysql2 to version v3.3.1, it seems work well.
So I want to know if I need some additional config when use v3.10.1

Here is error log

QueryFailedError: read ECONNRESET

  parameters: [ 'lijyze' ],

    fatal: true
  },
  errno: -4077,

}

I have read #2599 but still feel confused.
Any help would be appreciate！

Seems keepAliveInitialDelay cause this error, I have to pass a param to this config, and if I pass a small number, like keepAliveInitialDelay: 1, I also encounter this error. set it to 10000 seems work well.

Any explain about this?
