Sure, php-fpm.ini was set to (default I guess?) 128MB and I changed that to 512MB. For reasons I do not understand, the „systemchecker“ (is it called that way in English?) always showed the php memory as green so I never bothered d to look into it.
Sorry to re-awaken this old topic but I’m getting the same error when I try to update, now from 5.7.5 to 5.7.7 I have 768Mb as the PHP memory limit on Health Check - shouldn’t that be enough?
Has no entry for the time I tried the update 13:18 BST 2023-09-12
If there is anything I can try to help pin point the error willing to give it a go (for next upgrade) equally since you can’t reproduce can put up with command line upgrade preocess.
