This appears to happen randomly. ---Are there other PHP processes running for the same user with the same cache_id? I'm not sure about that. We do use 2 worker processes for the IIS application pool. We did try to use just 1, but the error happens with this configuration as well. ----Are there any relevant warnings in the OPcache error log? No, the OPcache error log only contains entries like: Message Cached script Message Added key Debug Loading blacklist file: ------------------------------------------------------------------------ [2021-03-15 09:17:01] cmb@php.net Does this happen after you modified some of the PHP files? Are there other PHP processes running for the same user with the same cache_id? Are there any relevant warnings in the OPcache error log? ------------------------------------------------------------------------ [2021-03-14 11:57:55] alex at ndros dot com Typo: we may get the same OR another class not found error. ------------------------------------------------------------------------ [2021-03-14 11:55:21] alex at ndros dot com Description: ------------ Hi, We're using PHP 7.4.16 NTS with Opcache. We randomly get "class not found" errors with the software that we run (Xenforo 2.2). For example: Class 'XF\Mvc\Entity\Repository' not found This is solved after an IIS reset, but after a few minutes, we may get the same on another class not found error. Our Opcache config is: [OPCACHE] zend_extension = "php_opcache.dll" opcache.memory_consumption=256 opcache.cache_id=node1 opcache.error_log="D:\temp\php\opcache.log" opcache.validate_timestamps=1 opcache.revalidate_freq=30 opcache.interned_strings_buffer=32 opcache.save_comments=0 opcache.max_file_size=0 opcache.file_update_protection=2 ;opcache.file_cache_consistency_checks=0 // not used ;opcache.file_cache="D:\temp\php\opcache_filecache" // not used opcache.max_accelerated_files=10000 opcache.log_verbosity_level=4 opcache.blacklist_filename= "D:\inetpub\wwwroot\******.com\conf\opcache\opcache-blacklist.txt" opcache.enable_cli=1 opcache.max_wasted_percentage=10 Thank you Alex Test script: --------------- We haven't found a specific way to reproduce the issue.
