Edit report at https://bugs.php.net/bug.php?id=77653&edit=1 ID: 77653 Updated by: bukka@php.net Reported by: claudiu_beta at yahoo dot com Summary: php-fpm, operator displayed instead of the real error message Status: Assigned Type: Bug Package: FPM related Operating System: Fedora 29 PHP Version: 7.3.3RC1 Assigned To: bukka Block user comment: N Private report: N New Comment: I just pushed another attempt to fix this to the PR. I also pinged Remi if he could kindly create another RPM to test. Previous Comments: ------------------------------------------------------------------------ [2019-05-05 15:59:59] bukka@php.net Ok thanks again for testing! Indeed it will result in quite a few new open file descriptor - basically one for each child in the master process which might be quite a lot if you are using around 1000 pools which means even more children. So this is not probably good idea either. So it seems like the markers in the output are the only possible solution for flushing. I think there are some issues in the logic atm. - the whole read loop is a bit messy so I will try to improve it and see if it addresses the issue. The thing that it definitely goes through that logic as the message is still decorated by zlog... ------------------------------------------------------------------------ [2019-05-05 09:44:20] claudiu_beta at yahoo dot com With this patch, now I have other bug and sites are completely down until php-fpm restart. A lot of lines like these. I never had this before. I have ~1000 pools using php7.3.
