framework: When running as daemon worker, there are SSL errors when attempting to send email

I think closing the connection after sending an email would be the correct way to fix this. At least it sounds more sane than trying to close the connection before sending an email and calling that a forced reconnection.

As @drcreazy’s solution seems to work I’ve submitted a corresponding pull request for the 5.1 branch (see https://github.com/laravel/framework/pull/13583). If approved I’ll submit the the changes for 5.0 and 5.2 as well.

Well, I tested all solutions include described in this thread

Seems the only appropriate solution is stopping transport after each task (it’s looks like the transport connects automatically on next task):

\Mail::getSwiftMailer()->getTransport()->stop();

I tried to reset daemons after couple failed attempts, but after some time I got timeouts errors from mailgun so it didn’t help me.

This is all my code for the job handler (worked fine in prod for a week, php7). Catching errors/stopping daemon instance seems unnecessary, but I keep it for now (hope they can helps somebody) :

public function sendOrderCompleted(RabbitMQJob $job, array $data)
    {
        try {
            \Mail::send(
                $data['template'],
                $data['body'],
                function ($message) use ($data) {
                    $message
                        ->to($data['to'])
                        ->subject($data['subject']);
                }
            );
        } catch (\ErrorException $e) {
            /**
             * Workaround
             *
             */
            if ($job->attempts() >= self::ATTEMPTS_BEFORE_EXIT) {
                $this->logger->info(
                    'Resetting daemon after ErrorException:'. $e->getMessage()
                    . 'Job: sendOrderCompleted. Job data: ' . json_encode($data)
                );
                // Attempts++
                $job->release();
                // Kill current daemon instance
                exit(0);
            }
            $this->logger->info('Catches ErrorException in sendOrderCompleted: ' . $e->getMessage());
            throw new \RuntimeException('ErrorException in sendOrderCompleted');
        } catch (\Throwable $e) {
            $this->logger->info(
                'Throwable in sendOrderCompleted: '
                . $e->getMessage()
                . ' Data: '
                . json_encode($data)
            );
            throw $e;
        }
        $job->delete();
        // stopping mail transport
        \Mail::getSwiftMailer()->getTransport()->stop();
    }

I had to restart every 15 min and seems to have been a good temp fix.
