Huge sustained CPU spike causes 504 error

  • Hi there,

    Since the issue is related to the resource usage, to solve the issue, I recommend asking at the hosting support to find more information on which processes that are using the most resources, and then try to solve the based on this information as most hosting provider should be able to provide such information.

    As additional information, for WordPress website there are some common processes that could cause resources spike, here are some of them:

    – wp_cron: This process is created by WordPress-based CronJobs and wp-cron file. To fix the issue from wp_cron, you can open your WordPress wp-config file and add this rule inside this file: define(‘DISABLE_WP_CRON’, ‘true’); After that WordPress CronJobs won’t be running automatically.
    – admin-ajax: This means that this issue was created by one or several of your website plugins when specific changes are done regarding these plugins or scheduled tasks are running. You can try to check how to fix this issue here: How to Reduce admin-ajax.php Server Load in WordPress

    Hope this helps.

    It was MailPoet! Had me looking for days. Now deleted and back down to a comfortable 3-5% CPU base instead of 50-60%!

    Ha, glad you were able to sort that out. Let us know here if this comes back. I’m marking this as resolved for now, but if you still keep running into issues, you know where to report it.

    All the best!
