MDVA-31519 patch: lost order after guest checkout

The MDVA-31519 patch solves the issue where paid orders are missing and lock wait timeouts in guest checkout.

This patch is available when the Quality Patches Tool (QPT) 1.0.14 is installed. Please note that the issue is scheduled to be fixed in Adobe Commerce version 2.4.3.

Affected products and versions

The patch is created for Adobe Commerce version:

Adobe Commerce on cloud infrastructure 2.3.5-p2

Compatible with Adobe Commerce versions:

Adobe Commerce on cloud infrastructure and Adobe Commerce on-premises 2.3.5 - 2.3.5-p2

The patch might become applicable to other versions with new Quality Patches Tool releases. To check if the patch is compatible with your Adobe Commerce version, update the magento/quality-patches package to the latest version and check the compatibility on the Quality Patches Tool: Search for patches page. Use the patch ID as a search keyword to locate the patch.


Steps to reproduce:

  1. Enable guest checkout.
  2. Create a cart price rule without a coupon (Example: “Free shipping above x amount”).
  3. Place a large amount of concurrent guest orders involving API payment Payment Service Providers (PSPs).

Expected results:

All paid payment transactions are saved to the database and visible in the Admin, as expected.

Actual results:

Only a small fraction of orders is saved in the database, while the majority of orders’ information is lost because of lock wait timeouts.
