I recommend to apply patches for #76601 on the top of it. It is made for 7.2.11 but can be applied to 7.1.23, 7.0.32, and 5.6.38 as well. ------------------------------------------------------------------------ [2018-07-11 08:28:40] mnikulin at plesk dot com It seems that combining the attached patch with the one from https://bugs.php.net/bug.php?id=76601 helps in the case of concurrent reload SIGUSR2 signals. At least it may be considered as quick plumbing. ------------------------------------------------------------------------ [2018-07-10 10:44:37] mnikulin at plesk dot com Let's start discussion in which way this bug can be fixed with a patch that uses sigprocmask() to block other reload signals during execvp() and early initialization. Do not use it in production. Instead of simply dead processes you may get more peculiar state described in https://bugs.php.net/bug.php?id=76601 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
