Preload Triggering Problem

  • Hi, I have some questions about preload logic.

    My setting for preload:

    • Refresh preloaded cache files every 60 minutes.
    • Preload all posts.
    • Checked – Preload mode
    • Checked – Preload tags, categories, and other taxonomies.
    • I have a cron job to trigger wp-cron.php every 5 minutes on my cpanel
    • Cache Timeout 259200 seconds
    • Garbage Collection Scheduler Once Daily 00:00

    1. The Triggering

    If I don’t click the Preload Cache Now button, the preload just never got triggered.
    If I click it, then it will get triggered and showing:

    Preload Active

    Currently caching from post 0 to 100.

    Page last cached: 18 https://xxx.com/product/%e6%b3%95%e5%9c%8b%e7%a6%a6%e7%8f%8d%e9%87%91%e6%a8%99%e7%b4%85%e8%91%a1%e8%90%84%e9%85%922013/

    And seems like the preload job takes forever to end.

    And I have 2 more questions from the debug log:

    2. It deletes non expired records

    It seems like the preload is deleting files that are not expired. It just simply rebuild everything. Is this the expected behavior? Should it be smart to skip non expired pages?

    3. Preload is stuck
    Seems like the preload process is stuck after this.

    7 minutes has passed, and preload page is still showing:

  • 1. Do you have problems with other wp-cron jobs? Do they trigger on time?
    2. Preload will create cache files for everything. Expired or not.
    3. Interesting. The last entry is “exiting as directory is not a directory”, which means it didn’t find a cached file there. That shouldn’t stop the preload as that happens all the time. Maybe there’s a problem with the wp-cron system on your site? It’s not scheduling the next job properly.

    But I have the cron job to run every 5 minutes. That’s how the first preload get start.

    I need to click preload cache now
    Then wait for the cron job to start
    So that the preload will actually start
