Previous Comments: ------------------------------------------------------------------------ [2017-01-26 11:05:33] albertcasademont at gmail dot com Yes please, a graceful reload is needed urgently. And more generally, php-fpm needs some love ------------------------------------------------------------------------ [2017-01-02 16:28:50] konrad dot baumgart at moneyhouse dot de This bug affects many people, but it seems the assigned person does not contribute to bugfixing anymore. Can we get it unassigned/reassigned? Bug is still present with nginx 1.10 and php 7 communicating with unix socket ------------------------------------------------------------------------ [2015-06-05 11:22:45] razvanphp at yahoo dot com I have the same problem with PHP 5.4.39-0+deb7u2, latest Debian Wheezy. Nginx mainline 1.9 uses unix socket connection to php-fpm, but it results in 502 when reloading php-fpm service. Found this in the code, that seems to cause this: static void sig_soft_quit(int signo) /* {{{ */ { int saved_errno = errno; /* closing fastcgi listening socket will force fcgi_accept() exit immediately */ close(0); if (0 > socket(AF_UNIX, SOCK_STREAM, 0)) { zlog(ZLOG_WARNING, "failed to create a new socket"); } fpm_php_soft_quit(); errno = saved_errno; } ------------------------------------------------------------------------ [2014-07-24 11:29:59] yinchuan at baixing dot com CentOS 6.5 + Nginx 1.4.7 + PHP 5.4.9 with php-fpm "fastcgi_keep_conn on;" in nginx.conf set pm.max_request=100, then when thd 100th reqest reach, php process exit, and nginx log error:"... recv() failed (104: Connection reset by peer) while reading response header from upstream, client: XXX" when set "fastcgi_keep_conn off;", everything is ok. ------------------------------------------------------------------------ [2014-02-19 19:35:47] ptr dot wang at gmail dot com php5-fpm 5.5.8+dfsg-3+sury.org~precise+2 on ubuntu precise has the same problem. killing USR2 signal to php5-fpm master process causes all php5-fpm processes (include the master process) replaced, and the active requests end up with HTTP 502 Bad gateway error on the nginx side. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
