Site health check widget and memcache

    Hi there,

    With memcache enabled in the plugin I don’t see any info in the health check widget in the WP dashboard.

    It just says:

    No information…Site health checks will automatically run periodically to gather information about your site. You can also visit the Site Health screen to gather information about your site now.

    The moment I turn memcache off, the widget now shows my site health status and my real-cron jobs run much closer to their set times.

    Good
    Great job! Your site currently passes all site health checks.

    I have been having major cron and cpu problems the last few days, which seem to have been solved by simply turning memcache off.

    Any ideas?

    Sean H.

    Memcached operates with certain amount of memory. When the objects that are cached there are too big that memory pool get’s filled up to the top and when the next object has to be stored, the previous one is removed so after a certain size of the objects you can get what you’re describing. The problem is that many WP plugin developers don’t even consider things as persistent object caching as long they have a working thing. We will be doing a massive overhaul of the Memcached service and the dropin we’re using but until then, you can just keep it off if it doesn’t play well with your site.

    Yes, I consider this thread resolved, but for the sake of conversation and anyone else who might be having the same issue, it would seem this problem is with WordPress itself, and not just my site.

    I’ve been running memcache fine on 11 sites, all with default WP cron in one GoGeek, up until the last WP 5.4 update. This would suggest something in WP core is causing this. Then again, more functionality might just require more power.

    So in my case, turning memcache off and setting up real crons fixed things for me, together with upgrading my 9 year old MacBook from 4GB to 16GB RAM. Things are now very snappy, back and front.
