I am running auction script through this but after running 12 hour got no response i have to use server.php start command again and again what is solution for this

<?php
use Workerman\Worker;
use Workerman\WebServer;
use Workerman\Autoloader;
use PHPSocketIO\SocketIO;

// composer autoload
include __DIR__ . '/vendor/autoload.php';
include __DIR__ . '/src/autoload.php';


require_once 'app/Mage.php';
//umask(0);
Mage::app();
Mage::getSingleton('core/session', array('name' => 'frontend'));




$io = new SocketIO(2020);


$io->on('connection', function($socket){
     $socket->addedUser = false;
     // when the client emits 'new bid', this listens and executes
      $socket->on('bid', function ($postdata)use($socket){
      Mage::getSingleton('core/session', array('name' => 'frontend'));
      $latency= ping(Mage::getBaseUrl(), 80, 10);
  }

}


$web = new WebServer('http://0.0.0.0:2022');
$web->addRoot('localhost', __DIR__ . '/public');

Worker::runAll();

here is my server.php status

Maybe your codes

Mage::getSingleton('core/session', array('name' => 'frontend'));
$latency= ping(Mage::getBaseUrl(), 80, 10);

caused the problem.

Try to remove them and do a test.

Mage::getSingleton('core/session', array('name' => 'frontend'));

This is php code cannot cause the problem. will check with

$latency= ping(Mage::getBaseUrl(), 80, 10);
and get back to you

I noticed 03:59:46.866050 write(2, "PDOStatement: MySQL server has g"..., 41) = 41 which means the connection of MySQL was killed by MySQL Server because the connection is idle for long time. That will cause the PDO throw a Exception, If your codes not catch the Exception the process will exit.
You can see /var/www/helpdesk/socket/vendor/workerman/workerman.log for detail.

Good morning, @walkor.
So, I shouldn't have a permanent PDO connection on socket server, right?
If I create and close the PDO connections only where I need instructions, it must works?
