HapiJS＆MySQL在一段時間後崩潰

Question

我的HapiJS + MySQL服務器在大量請求後不斷崩潰。

const MySQL= require('mysql'); 
const pool = MySQL.createPool({ 
     host  : 'localhost', 
     user  : 'aUser', 
     password : 'aPWD', 
     database : 'DB' 
    })}; 

pool.getConnection(function(err, connection) { 
    query = 'SOMETHING'; 

    connection.query(query,function (error, results, fields){ 
       connection.release(); 
       reply(results); 

    }); 

}); 

我的感覺是錯誤發生，因爲池用完了連接？ 由於未定義connection而失敗。

這裏的錯誤：

我被與價值/var/run/mysqld/mysqld.sock添加socketPath到數據庫配置

const MySQL= require('mysql'); 
    const pool = MySQL.createPool({ 
      host  : 'localhost', 
      user  : 'aUser', 
      password : 'aPWD', 
      database : 'DB', 
socketPath:'/var/run/mysqld/mysqld.sock' 
     })}; 

    pool.getConnection(function(err, connection) { 
     query = 'SOMETHING'; 

     connection.query(query,function (error, results, fields){ 
        connection.release(); 
        reply(results); 

     }); 

    });
