Php Opcache自清除并中断代码执行

我有一个Magento 2存储，但这似乎是一个PHP问题，启用了opcache，有时opcache似乎会自行清除，如果无法执行某些操作，我最终会创建一个存储。有时，当我手动清除opcache时，我也会收到错误和存储，而不是完全脱机，根据错误，某些操作无法执行。有时我无法将产品添加到购物车或下订单。这些错误与下面的错误类似：

[2020-06-09 18:20:38] main.CRITICAL: Warning: preg_match(): Compilation failed: unmatched parentheses at offset 36 in /home/store/public_html/vendor/magento/zendframework1/library/Zend/Locale/Format.php on line 527 {"exception":"[object] (Exception(code: 0): Warning: preg_match(): Compilation failed: unmatched parentheses at offset 36 in /home/store/public_html/vendor/magento/zendframework1/library/Zend/Locale/Format.php on line 527 at /home/store/public_html/vendor/magento/framework/App/ErrorHandler.php:61)"} []

以下是我的opcache配置：

自动操作缓存代码刷新似乎每隔一周发生一次，但不是在一天中的特定日期或时间

我在PHP日志中没有关于opcache错误的日志

为什么opcache会在有大量可用空间和内存的情况下自行清除，为什么清除opcache可能会导致看起来像是坏掉的缓存代码
