PHP错误的文件描述符错误 [英] PHP Bad File Descriptor Error

问题描述

我们最近已将服务器从PHP 5.4.15升级到5.5.1，并已开始在日志中获取此错误

We've recently upgraded our servers from PHP 5.4.15 to 5.5.1 and have started getting this error in the logs

致命错误无法创建锁定文件:错误的文件描述符

Fatal Error Unable to create lock file: Bad file descriptor

我已经跟踪到了这一点，该代码打开了另一个小的PHP脚本，该脚本将文件上传到后台的S3中.

I've tracked it down to this bit a code that opens another small PHP script which uploads a file to S3 in the background.

// Grab uploaded file and assign a working name
$fileTemp = $_FILES['file']['tmp_name'];
$pathToWorkingFile = tempnam($g_TmpDirectory, "TR-");

// Move the file to our working area        
if (move_uploaded_file($fileTemp, $pathToWorkingFile) === false)
    throw new Exception("Cannot move file to staging area.", 1011);

// Where the file will end up on S3
$s3Bucket = "test.bucket.com";
$uploadDest = "/uploads/image123.jpg";

// Create process to upload file in background
popen("/usr/local/bin/php /path/to/uploadScript.php $pathToWorkingFile $s3Bucket $uploadDest &", 'r');

推荐答案

事实证明，此错误是由我们在PHP升级过程中启用的OPcache配置引起的.当我通过从php.ini中删除此设置来禁用命令行操作时，一切正常.

It turns out that this error was caused by our configuration of OPcache which was enabled during the PHP upgrade process. When I disable it for command line operations by removing this setting from php.ini everything works fine.

opcache.enable_cli=1
