Preloading is scheduled multiple times

Hello,

I have configured the status emails for the start and end of preloading and noticed that the preloading task is often executed multiple times in a row. If this is happen the preloading takes a very long time (Up to one hour instead of a few minutes). I have set up a cache renewal every 120 minutes. I suspect the cause of both the repeated executions and the long runtime is that the wp_cache_full_preload_hook task is scheduled 2 to 3 times.

I have disabled the default cron job in the wp_config.php file (define( ‘DISABLE_WP_CRON’, true )) and instead, I am using a Windows task that runs every 5 minutes (powershell “Invoke-WebRequest -UseBasicParsing http://localhost/wordpress/wp-cron.php”) on my IIS Server. I Checked the schedules with the plugin “Advanced Cron Scheduler”.

Best regards

Raik
