Title: Huge number of Scheduled actions being generated Last modified: August 14, 2025 --- # Huge number of Scheduled actions being generated * Resolved [fishyfighter](https://wordpress.org/support/users/fishyfighter/) * (@fishyfighter) * [1 year ago](https://wordpress.org/support/topic/huge-number-of-scheduled-actions-being-generated/) * Hi all, * I’ve got a reasonably sized woocom site and its run well for years. Since Thursday I’m getting a huge amount of scheduled actions been generated with the following– * Hook – wc_delete_related_product_transients_async * Group – wc_delete_related_product_transients_group Non repeating * Its related to individual product ID’s but doesn’t specify what its actually doing. Some complete, some fail and there is also a queue in past due. Totalling around 5.5 million. * I’ve tried the basics of clearing transients with no effect, I’ve also run the auto cron tool restart a process. It starts it again but then slows up and stops again. /wp-cron.php?doing_wp_cron * I’ve also got a message saying – Action Scheduler migration in progress. The list of scheduled actions may be incomplete. Woo AI tells me woocomerce is moving data between tables to make it more efficient. Any help is greatly appreciated.

The issue you’re seeing with millions of scheduled actions related to `wc_delete_related_product_transients_async` is tied to WooCommerce clearing cached “related products” data. This can happen in bulk if many products were recently updated or affected by a plugin or import. * The “Action Scheduler migration in progress” message means WooCommerce is moving scheduled actions to a more efficient system. During this time, things can slow down or seem stuck. If the queue is massive, it can overwhelm your site and cause timeouts or delays. * To get things back under control, I recommend running a real cron job on your server instead of relying on the default WP-Cron, as this is more reliable for processing large queues. You can also temporarily cancel or clear the related scheduled actions using a plugin like Action Scheduler or WP Crontrol. Additionally, optimizing your database to remove expired transients and checking if any plugins triggered bulk updates recently would help. * If you’re still stuck after trying these, let me know more about your website setup by sharing your system status report from WooCommerce > Status > get report > copy for support and share it via gist.github.com. * Additionally can you explain how products on your site is updated? Is it manually through edits, or via csv import or automated via API or other platforms? - This reply was modified 1 year ago by [Moses M.

Having the same issue on one of my WC sites. With around 500k lines since Friday 11/04/2025. For the moment I have cleaned them out: ` wp action-scheduler clean --batch-size=1000 --status=pending`and the site works again (since it was timing out all the time) but I can see those same jobs for“ wc_delete_related_product_transients_async” building up and piling up again… * [Joris Le Blansch](https://wordpress.org/support/users/apiosys/) * (@apiosys) * [1 year ago](https://wordpress.org/support/topic/huge-number-of-scheduled-actions-being-generated/#post-18415663) * To follow-up on this, after initial cleanup of the tasks, and seeing them piling up again, I went through testing one plugin at a time and for me it seemed that the plugin “**WC Currency Switcher**” was the culprit here. At least leaving it OFF instantly stops the jobs “wc_delete_related_product_transients_async” from being created a few times per minute… [@fishyfighter](https://wordpress.org/support/users/fishyfighter/), do you have that plugin ? I could see the prices on your website only in GBP but maybe you have it running in the background? * Thread Starter [fishyfighter](https://wordpress.org/support/users/fishyfighter/) * (@fishyfighter) * [12 months ago](https://wordpress.org/support/topic/huge-number-of-scheduled-actions-being-generated/#post-18416768) * I’m still struggling to locate which plugin is causing this. Is there a way to look at a scheduled action in more detail? * [Moses M.

I had shared a reply before [@apiosys](https://wordpress.org/support/users/apiosys/) contributed to the thread. Kindly review it, follow the instructions provided, and respond to the questions that were asked. * Thread Starter [fishyfighter](https://wordpress.org/support/users/fishyfighter/) * (@fishyfighter) * [12 months ago](https://wordpress.org/support/topic/huge-number-of-scheduled-actions-being-generated/#post-18417092) * Thanks for quick response. I’m a little new to github. I’ve got my system report copied for github but where to a post it? Does it need to be secure? * Plugin Support [LovingBro (woo-hc)](https://wordpress.org/support/users/lovingbro/) * (@lovingbro) * [12 months ago](https://wordpress.org/support/topic/huge-number-of-scheduled-actions-being-generated/#post-18417108) * Hi [fishyfighter](https://wordpress.org/support/users/fishyfighter/), * Great to hear you’ve got your system status report ready! Instead of using GitHub Gist (which requires an account), I recommend sharing it through one of these simpler options: - **[https://quickforget.com](https://quickforget.com)** - **[https://pastebin.com](https://pastebin.com)** * Both allow you to paste your report without needing to sign up. When creating your link, be sure to increase the number of **views allowed** and **set the expiry date** to at least **7 days**—this ensures we have enough time to review it properly. * Once you’ve done that, just share the link here and we’ll take a closer look. Looking forward to helping you sort this out! * Plugin Support [shahzeen(woo-hc)](https://wordpress.org/support/users/shahzeenfarooq/) * (@shahzeenfarooq) * [11 months, 2 weeks ago](https://wordpress.org/support/topic/huge-number-of-scheduled-actions-being-generated/#post-18446836) * Hi [@fishyfighter](https://wordpress.org/support/users/fishyfighter/) I would like to inform you that our developers are already aware of the issue, and they are hoping to fix it in version 9.9.0.
