Cache is Full Warnings – Even after Optimizing Server Opcache Setup

    Thank you for you great job on this mod.

    I’ve being using this plugin for about 6 months combined with your APCu Manager plugin with decent results.

    During this period, this plugin was not giving better server performance but also a good tool for tweaking Opache settings for getting even better.

    Only one thing that keeps me warning is “Cache is full” several warnings during the day and despite everything I did so far, I’ve can’t get rid of those.

    Any tips about that would be very much helpful.

    Hello Leo,

    And thank you for your kind words.

    What you are seeing in this dashboard is typical of the “insufficient memory allocated to OPcache” syndrome: weak hit rate, inconsistent graph, no free memory and buffer saturated to its maximum… Yes, cache is really full, and that’s not good!

    I suggest that you check (and increase accordingly) the following values in php.ini (or whatever the location where you can specify php settings): opcache.max_accelerated_files, opcache.interned_strings_buffer and opcache.memory_consumption until you consistently get more than 30% of free memory, and buffer saturation at less than 80%.

    Hope it helps.

    Dear @pierrelannoy,

    Thank you for your reply. Despite of setting up all Opcache variables at PHP.ini correctly as you suggested, even before posting this one for some help, checking OPcaching settings with PHPinfo simple file, I’ve found out that my server parsed OPcache settings not only from php.ini but also through another Opache.ini particular file.

    Set this one to same php.ini opcache file and it worked like a charm. No more “cache is full” messages and free memory around 30 and buffer around 80.

    Posting final solution here may help others with same issues.

    Thanks again and keep up your fantastic job.
