It looks like this could be a PHP bug. In the latest changelog for 7.1.13 release of PHP there are two fixes for this error: http://php.net/ChangeLog-7.php#7.1.13

Hello @rigu12,

This is not a solution to the bug of PHP 7.1.12, but can help you to avoid this warning while coming out a patch or a new version (I suppose it could be solved then).

The problem is with the OPCache library, that "... improves PHP performance by storing precompiled script bytecode in shared memory..." more info: http://php.net/manual/en/intro.opcache.php.

The "solution" is clear the cache when the application is loaded. This is easy if you have an "single entry point" application (when you use a framework, for example). Just put the next function at the beginin of your index.php (or equivalent) file:

opcache_reset();

I'm not sure that this could be used in production servers, because could turn the application heavy.
