Bug #80341 [NEW]: OPCache wasted memory grows rapidly and no restart after max_wasted_percentage

From: alex at ndros dot com Operating system: Windows 2019 PHP version: 7.4.12 Package: opcache Bug Type: Bug Bug description:OPCache wasted memory grows rapidly and no restart after max_wasted_percentage Description: ------------ I run PHP 7.4.12 on a Windows 2019 IIS10 server. The wasted memory value in PHP Opcache grows rapidly, fills up my entire 2GB allocated to Opcache, and then opcache stops working. For example, these are the statistics after 30mins since the last webserver reset: total memory: 2.00GB used memory: 89.00MB free memory: 1.66GB wasted memory: 261.36MB (12.76%) And these are my settings: opcache.memory_consumption=2048 opcache.cache_id=oc1 opcache.error_log="D:\temp\php\opcache_errors.log" opcache.validate_timestamps=1 opcache.revalidate_freq=90 opcache.interned_strings_buffer=32 opcache.save_comments=0 opcache.max_file_size=0 opcache.file_update_protection=0 opcache.file_cache_consistency_checks=0 opcache.file_cache="D:\temp\php\opcache_filecache" opcache.max_accelerated_files=100000 If I leave it to run more time, the wasted memory fills up my entire 2GB allocated to Opcache, and opcache will simply stop to work. I can verify this be updating .php files and the changes show up instantly (where normally they take 90 seconds or less, based on my opcache.revalidate_freq).
