Thanks, @vmarko. The last thing I wanted to know is whether these cache files can be targeted/exploited in any way by an attacker because I see multiple post requests to these files and a few of them returned HTTP 200 on my server. And this is the same time my website starts showing error and in my server logs I can see this kind of error:
<trimmed> FastCGI sent in stderr "PHP message: PHP Fatal error: Uncaught Error: Function name must be a string <trimmed>
My website goes offline until I restart my PHP fpm service and every request to my website generates the above error.
And, I will work on your feedback on using memory-based caching.
Thanks!
