            Amp\async(function () use ($args , $atomicrunningCoroutines, $pm_pid) {
  
                PrintLog( 'add ' . $pm_pid );
                $context = Amp\Parallel\Context\contextFactory()->start(__DIR__ . '/child/sms_send_select.php');
                $context->send($args);
                $returnValue = $context->join();
                printf("%s processes exited with '%s'\n",  $pm_pid , $returnValue);

            });

Hi @parsibox!

This error is the result of the parent processing being unable to write to STDIN of the child process before the child process fails. I have no idea why that might be happening on your system. A quick Google search of the error you posted indicates it potentially could be due to a hardware issue or configuration/permission issue.

Do you have another system you could test on? Anything configured like a firewall or process watcher that could interfere?
