Title: Overload server Last modified: October 16, 2017 --- # Overload server * Resolved [lucasaguiar](https://wordpress.org/support/users/lucasaguiar/) * (@lucasaguiar) * [8 years, 8 months ago](https://wordpress.org/support/topic/overload-server-2/) * Hi, I’m having trouble at my site, and the developer suspect that its a problem with MailChimp plugin. * Some plugin (and probably MailChimp plugin) is making a lot of requests to admin- ajax.php and overload the server …. * The call that cause the problem was: * 37.60.234.129 – – [16/Oct/2017:07:16:37 -0500] “POST /wp-admin/admin-ajax.php? action=http_worker&nonce=a96e96ca1d HTTP/1.0” 200 – “[https://www.domain.com/wp-admin/admin-ajax.php?action=http_worker&nonce=a96e96ca1d”](https://www.domain.com/wp-admin/admin-ajax.php?action=http_worker&nonce=a96e96ca1d”);“ WordPress/4.8.2; [https://www.https://www.domain.com”](https://www.https://www.domain.com”); * If you Google action=http_worker&nonce you will find it: * [https://github.com/mailchimp/mc-woocommerce/issues/100](https://github.com/mailchimp/mc-woocommerce/issues/100) * [https://wordpress.org/support/topic/error-php-message/](https://wordpress.org/support/topic/error-php-message/) * Does somebody knows how to solve is? Is it a problem with MailChilp? * Tks, * Lucas.

Downgrading from Woocommerce 3.2.1 to 3.1.2 seems to have helped but not sure, it’s only been a few hours and waiting to see if it will spike again or not. Issue happened a couple days ago after upgrading some plugins and adjusting some settings so not sure if the Woocommerce update caused the conflict or not. * [ianatkins](https://wordpress.org/support/users/ianatkins/) * (@ianatkins) * [8 years, 7 months ago](https://wordpress.org/support/topic/overload-server-2/#post-9612797) * Likewise, after installing WP Crontrol to look into the issue – the http_worker_cron cron task (set by this plugin) was set to run every 3 minutes!? * Am disabling the plugin until some sane limits are put in place, maybe an update every hour – 12 hours? * [PthPndr](https://wordpress.org/support/users/pthpndr/) * (@pthpndr) * [8 years, 7 months ago](https://wordpress.org/support/topic/overload-server-2/#post-9645991) * We are having the same problem. Ended up having to disable this plugin. Has anyone found another cause or is this plugin pretty much it? * Thread Starter [lucasaguiar](https://wordpress.org/support/users/lucasaguiar/) * (@lucasaguiar) * [8 years, 7 months ago](https://wordpress.org/support/topic/overload-server-2/#post-9646071) * Where is MailChimp support? * [Nikita](https://wordpress.org/support/users/delfniki/) * (@delfniki) * [8 years, 7 months ago](https://wordpress.org/support/topic/overload-server-2/#post-9652707) * Hi same here…site was already 2x blocked by siteground… I tried to adjust the cron settings from 3 minutes to half an hour, but it did not work. * [mcsupport](https://wordpress.org/support/users/mcsupport/) * (@mcsupport) * [8 years, 7 months ago](https://wordpress.org/support/topic/overload-server-2/#post-9654975) * Hey everyone, thanks for continuing to keep this thread updated. * Given that this issue seems to be presenting itself on the backend, I would recommend reaching out in [our Github for the plugin to share these issues directly with our development team](https://github.com/mailchimp/mc-woocommerce/issues/). Including this logging as well as the [WooCommerce System Status Report](https://docs.woocommerce.com/document/understanding-the-woocommerce-system-status-report/) to share your site’s details will be a great help in getting things accurately diagnosed. * If you do encounter any unexpected behavior with the plugin’s functionality or how it’s sending information back over to MailChimp, please don’t hesitate to let me know. I’m glad to help further however possible. * – Malachite Viewing 6 replies - 1 through 6 (of 6 total) The topic ‘Overload server’ is closed to new replies. * ![](https://ps.w.org/mailchimp-for-woocommerce/assets/icon-256x256.png?rev=1509501) * [Mailchimp for WooCommerce](https://wordpress.org/plugins/mailchimp-for-woocommerce/) * [Frequently Asked Questions](https://wordpress.org/plugins/mailchimp-for-woocommerce/#faq) * [Support Threads](https://wordpress.org/support/plugin/mailchimp-for-woocommerce/) * [Active Topics](https://wordpress.org/support/plugin/mailchimp-for-woocommerce/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/mailchimp-for-woocommerce/unresolved/) * [Reviews](https://wordpress.org/support/plugin/mailchimp-for-woocommerce/reviews/) * 6 replies * 6 participants * Last reply from: [mcsupport](https://wordpress.org/support/users/mcsupport/) * Last activity: [8 years, 7 months ago](https://wordpress.org/support/topic/overload-server-2/#post-9654975) * Status: resolved
