The value -1 does not mean unlimited in BSD but it can continuously go on for a long long time which is why it is important to keep the documentation the way it is. If we changed everything over some minor details we would have successfully deleted the documentation. What I recommend is changing BSD to accept it as "unlimited". One and done. ------------------------------------------------------------------------ [2019-09-30 08:45:07] [email protected] https://www.php.net/manual/en/install.fpm.configuration.php > listen.backlog int > Set listen(2) backlog. A value of '-1' means unlimited. Default value: -1. > In BSD, the default value is -1, but it does not mean "unlimited". Source? Neither the FreeBSD, NetBSD, nor OpenBSD manpages talk about a backlog <= 0. Meanwhile die.net's POSIX docs say such a backlog "may be set to an implementation-defined minimum value". Unless you're talking about the literal meaning of not having any limit whatsoever? Which obviously could not be the case. ------------------------------------------------------------------------ [2019-09-30 05:34:24] psi at 7io dot org Description: ------------ As described in this code: https://github.com/php/php-src/blob/1ad08256f349fa513157437abc4feb245cce03fc/sapi/fpm/fpm/fpm_sockets.h#L17 the default value of "listen.backlog" in php-fpm.conf is not -1. It is 511. In BSD, the default value is -1, but it does not mean "unlimited". Please see here(freebsd): https://www.freebsd.org/cgi/man.cgi?listen(2)#end ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78611&edit=1
