Seu sistema ficou sem memória O erro 12 é o sinal de kernel do ENOMEM.
Depois de configurar o listener de fila para processar vídeos enviados com o FFMPEG, voltei ao servidor várias vezes para descobrir que o MySql parou de funcionar. Eu verifiquei o espaço da unidade e é cerca de 77% usado (43G de 60G).
Aqui está o meu código, caso seja útil:
public function fire($job, $data)
{
$data = json_decode($data['transcoding_message'], true);
$output_directory = '/home/ubuntu/transcodes/';
$amazon_array = array();
$s3 = AWS::get('s3');
//execute main transcoding thread
$cmd = 'sudo ffmpeg -i ' . $data['temp_file_url'] . ' -y -vcodec libx264 -tune zerolatency -movflags faststart -crf 20 -profile:v main -level:v 3.1 -acodec libfdk_aac -b:a 256k ' . $output_directory. $data['temp_file_key'] . '_HQ.mp4 -vcodec libx264 -s ' . $sq_width . 'x' . $sq_height . ' -tune zerolatency -movflags faststart -crf 25 -profile:v main -level:v 3.1 -acodec libfdk_aac -b:a 256k ' . $output_directory. $data['temp_file_key'] . '_SQ.mp4 -ss ' . $seek_half . ' -f image2 -vf scale=iw/2:-1 -vframes 1 ' . $output_directory. $data['temp_file_key'] . '_thumb.jpg';
exec($cmd." 2>&1", $out, $ret);
if ($ret)
{
Log::error($cmd);
echo 'Processing error' . PHP_EOL;
//there was a problem
return;
}
else
{
//setup file urls
echo 'about to move files';
$hq_url = $this->bucket_root . $data['user_id'] . '/' . $data['temp_file_key'] . '_HQ.mp4';
$sq_url = $this->bucket_root . $data['user_id'] . '/' . $data['temp_file_key'] . '_SQ.mp4';;
$thumb_url = $this->bucket_root . $data['user_id'] . '/' . $data['temp_file_key'] . '_thumb.jpg';
$amazon_array['video_hq_url'] = $data['temp_file_key'] . '_HQ.mp4';
$amazon_array['video_sq_url'] = $data['temp_file_key'] . '_SQ.mp4';
$amazon_array['video_thumb_url'] = $data['temp_file_key'] . '_thumb.jpg';
//copy from temp to permanent
foreach ($amazon_array as $k => $f)
{
$uploader = UploadBuilder::newInstance()
->setClient($s3)
->setSource($output_directory.$f)
->setBucket($this->bucket)
->setKey('users/' . $data['user_id'] . '/' . $f)
->setConcurrency(10)
->setOption('ACL', 'public-read')
->build();
$uploader->getEventDispatcher()->addListener(
'multipart_upload.after_part_upload',
function($event) use ($f) {
// Do whatever you want
}
);
try {
$uploader->upload();
echo "{$k} => Upload complete.\n" . PHP_EOL;
DB::table('items')->where('id', $data['item_id'])->update(array($k => $this->bucket_root. $data['user_id'] . '/' .$f, 'deleted_at' => NULL));
//delete local
unlink($output_directory.$f);
unset($uploader);
} catch (MultipartUploadException $e) {
$uploader->abort();
echo "{$k} => Upload failed.\n" . PHP_EOL;
continue;
}
}
//write to database
DB::table('archives_items')->where('id', $data['archive_item_id'])->update(array('deleted_at' => NULL));
DB::connection('mysql3')->table('video_processing')->where('id', $data['id'])->update(array('finished_processing' => 1));
//delete files
//delete s3
$s3->deleteObject(
array(
'Bucket' => $this->temp_bucket,
'Key' => $data['file_name']
)
);
echo $data['temp_file_url'] . '=>' . " deleted from temp bucket.\n" . PHP_EOL;
DB::connection('mysql3')->table('video_processing')->where('id', $data['id'])->update(array('deleted_at' => \Carbon\Carbon::now()));
}
$job->delete();
// end of processing uploaded video
}
else
{
return;
}
Alguma idéia do motivo pelo qual o MySql morreria assim?
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (111)
Eu quero mencionar que o comando php artisan queue: listen está sendo acionado via Supervisor e que eu tenho 4 processos concorrentes em execução.
