Recently upgraded all of our firewalls to 2.3.3-RELEASE-p1. Out of the bunch, one seems to be misbehaving post-upgrade. I'm greeted with a 502 nginx error and have to SSH in to restart webGUI and PHP-FMF (11 & 16).
My log gets flooded with these messages:
nginx: 2017/04/06 07:59:32 [error] 69650#100123: *22421 connect() to unix:/var/run/php-fpm.socket failed (61: Connection refused) while connecting to upstream, client: <ip address="">, server: , request: "GET /getstats.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php-fpm.socket:", host: "<ip address="">", referrer: "https://<ip address="">/index.php"</ip></ip></ip>
It's followed by a kernel messgae:
Apr 6 08:00:05 kernel sonewconn: pcb 0xfffff8006121fe10: Listen queue overflow: 193 already in queue awaiting acceptance (6 occurrences)
This redmine case might be related, however it is not occurring on all of my firewalls if this is a software bug.
