Previous Comments: ------------------------------------------------------------------------ [2020-12-18 16:05:55] tobias dot nyholm at gmail dot com In a different application I got more zend_mm_heap corrupted errors. The application seams to be running fine, but having a corrupted heap is never fun. After disabling preloading, the error message went away. Ideally I'll provide you with a small reproducer, but I have not been able to create one. The application in question is open sourced and running on Symfony cloud.
