    Hi,

    We have w3tc pro version, we have the redis cache implemented and we are seeing current items keeps piling up and the memory is reaching 100% (m6g.large – 6GB mem) and its getting filled. We have provisioned this only for Page Cache and Maximum lifetime of cache objects set is 24hours.

    This is bringing down our site continuously because of the issue.

    Please help us at the earlierst.

    Thanks,

    Hello @naveen8878

    Thank you for reaching out.

    The most likely reason for this is the maximum lifetime of objects you’ve set

    The default is 3600s and if you have a big website, with a lot of updates ad the cache is purged occasionally, the _old files may remain there piling up in the memory.
    Now the “maximum lifetime of objects” is added with the compatibility mode option and it’s shown only when disk-enhanced is used. If you have had Disk: Enhanced enabled and then switched to Redis else there is a possibility that the Compatibility mode was selected and now affects browser cache rules historically.
    Two things that you can do potentially. You can switch back to Disk: Enhanced save all settings and then disable compatibility mode, save all settings, and purge caches. The other thing that you can do is to manually remove W3TC rules from .htaccess and leave the .htaccess only with WP default rules. This will allow W3 Total Cache to write new set of rules to your .htaccess file.
    I hope this helps!

    Thanks!
