Authorize.net payhment received but no order in database

[jeking]

This has happened twice now. A payment is processed in Authorize.net but there is no order in Zen Cart. I know the payment is from Zen Cart because of the order ID reported, 5365-AiiwHj. 5365 is the next order number in Zen Cart, but there is no such order number.

The site is a recent upgrade, 1.5.7c from 1.5.6a
Using Authorize.net (AIM)
PHP 7.4.22
Session settings: https://screenrec.com/share/TdE9bq6S0H
curltester.php returns all "Good" results

I have not seen this problem before. Suggestions?

Did you check for debug logs? If you run an order with a different payment method like Check/Money Order, does everything work properly?

Debug logs generated?
First thought is to go ahead and do a remove and reinstall of the payment plugin (taking note of all the settings before doing so) and possibly backing up the database.

Appears there is something that is going wrong during the checkout_process or checkout_success steps. If I remember correctly this is a lot like the issue that occurs with say PayPal standard where information is captured and passed around a little, but an issue occurs before ZC is notified of the successful transactions and then takes action to log the purchase. Sometimes the issue in that case is with the email account, sometimes with storage availability and sometimes just doesn't work out or get alignment of the purchase info with what has been captured about the purchase.

For cases like these, I normally check the site's hosted "Raw Access Logs" to see how the customer traversed through the site when the issue occurred.

Thank you for the suggestions. Looking at the logs folder, I am seeing a few different errors related to sessions and memory issues but I think there is a different underlying problem. PHP is set for 128M. I'd doing a little more digging.
