Bug #78106 [Asn]: PHP Fatal error: Uncaught Error: Class 'Phpfastcache\Config\Config' not found

Edit report at https://bugs.php.net/bug.php?id=78106&edit=1 ID: 78106 User updated by: mbiebl at messageconcept dot com Reported by: mbiebl at messageconcept dot com Summary: PHP Fatal error: Uncaught Error: Class 'Phpfastcache\Config\Config' not found Status: Assigned Type: Bug Package: opcache Operating System: Windows Server 2016 / IIS 10 PHP Version: 7.2.19 Assigned To: dmitry Block user comment: N Private report: N New Comment: I've changed my php.ini to enable debug logging for opcache like this: ``` zend_extension=php_opcache.dll opcache.enable_cli=1 opcache.enable=1 opcache.error_log="C:\Windows\temp\php_opcache.log" opcache.log_verbosity_level=4 ``` Unfortunately, this didn't produce any useful log messages. I only get messages like this: ``` Wed Jun 12 17:11:38 2019 (4748): Message Cached script 'C:\src\server\localhost\vendor\psr\log\Psr\Log\LoggerInterface.php' Wed Jun 12 17:11:38 2019 (4748): Message Added key 'C:\src\server\localhost\vendor\composer/../psr/log/Psr/Log\LoggerInterface.php' ``` Also, this is only for one php process (4748), while I have multiple processes.

Maybe a lower level is enough to log non-user restarts, but I'm not sure. ------------------------------------------------------------------------ [2019-06-11 19:59:24] mbiebl at messageconcept dot com How can I find out if there was an opcache restart? Is there a way to get a more verbose debug log from the opcache module? ------------------------------------------------------------------------ [2019-06-11 13:28:31] nikic@php.net Thanks for the information! If this issue only occurs sporadically, is there any correlation with opcache restarts? That is, does the error occur around the same time that an opcache restart even occurs? ------------------------------------------------------------------------ [2019-06-11 13:26:42] dmitry@php.net May be this patch can help https://gist.github.com/dstogov/b13163408e0edf337b99b4e634cba38f But it's really hard to guess, without a way to reproduce the problem. ------------------------------------------------------------------------ [2019-06-11 13:08:48] michel at weimerskirch dot net I was lead to this issue from here: https://github.com/php/php-src/pull/4161 Our setup on the affected machines is PHP 7.2.19 or 7.3.6 with opcache enabled. Deactivating opcache or going back to 7.2.18 or 7.3.5 also "solve" the problem for us, just like for the user "ani2life". As to the ini configuration, we tried a few combinations, but even with everything set to default the error sometimes appears. Yes, we run FPM on Ubuntu. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
