Expected duration: less than 1 week We are having issues with Magento 1.9.2.4. A small percent of customers are getting 504 errors. These continue until cookies are cleared (in particular the frontend_cid cookie).
Here is a sample of the corresponding errors in our log: [17-Sep-2020 08:43:22 UTC] PHP Fatal error: Maximum execution time of 50 seconds exceeded in /http/lib/Credis/Client.php on line 1168 [17-Sep-2020 08:46:38 UTC] PHP Fatal error: Maximum execution time of 50 seconds exceeded in /http/lib/Zend/Db/Statement/Pdo.php on line 228 [17-Sep-2020 08:49:16 UTC] PHP Fatal error: Maximum execution time of 50 seconds exceeded in /http/lib/Varien/Simplexml/Element.php on line 195 [17-Sep-2020 08:50:05 UTC] PHP Fatal error: Maximum execution time of 50 seconds exceeded in /http/app/code/core/Zend/Db/Select.php on line 1170 [17-Sep-2020 08:50:05 UTC] PHP Fatal error: Maximum execution time of 50 seconds exceeded in /http/lib/Varien/Data/Collection.php on line 562
The file name in the logs varies.
We don't have exact steps to recreate the issue but it seems like it could be related to having items in the cart and/or switching stores.
