What does this mean?

    I just installed WP Crontrol to get more info on what’s happening. I noticed some interesting things around W3 Total Cache…

    First off, the top of the plugin page shows “There was a problem spawning a call to the WP-Cron system on your site. This means WP-Cron events on your site may not work. The problem was: cURL error 28: Operation timed out after 3001 milliseconds with 0 bytes received“.

    1. Problematic intervals:

    For these three “names”…

    – w3_cdn_cron_queue_process ([W3TC] CDN queue process (disabled))
    – w3_cdn_cron_upload ([W3TC] CDN auto upload (disabled))
    – w3_fragmentcache_cleanup ([W3TC] Fragment Cache file GC (disabled))…

    WP Crontrol’s “Interval” column reads: “0 (now) This interval is less than the WP_CRON_LOCK_TIMEOUT constant which is set to 60. Events that use it may not run on time.”

    see https://i.imgur.com/dD5tKTJ.png

    Other W3-related names (w3_dbcache_cleanup, w3_objectcache_cleanup, w3_pgcache_cleanup, w3_minify_cleanup and w3_pgcache_prime) each show with the relevant time interval.

    2. Event listings:

    In WP Crontrol’s list of actual “Cron Events”, the W3-related hook w3_fragmentcache_cleanup shows with “None” in the action column.

    see https://i.imgur.com/smaTioh.png

    Of the other W3-related hooks (w3_objectcache_cleanup, w3_dbcache_cleanup, w3_pgcache_prime, w3_pgcache_cleanup, w3_minify_cleanup), they do not show a problem.

    What is going on here? Something doesn’t seem right.

    There was a problem spawning a call to the WP-Cron system on your site – You’ll need to speak to your host about this problem.

    1. Problematic intervals: You’ll need to speak with W3TC about this. An interval of 0 is useless, so the schedule should be removed.

    2. Event listings: Again maybe something to ask W3TC about. An event with no action is also useless, although there is a small chance that an action gets conditionally added to this event by a plugin based on a setting, for example, and thee plugin isn’t correctly handling the scheduling or unscheduling of the event.
