Occassional 502 Gateway error with LEMP
Some people are reporting that my LEMP website is giving a 502 error. I’ve seen this myself from one public wifi point. I never see it anywhere else. My logs are filled with these errors:
2016/08/16 06:59:02 [error] 3618#0: *1445992 connect() to unix:/var/run/php5-fpm.sock failed (11: Resource temporarily unavailable) while connecting to upstream, client: 126.96.36.199, server: 188.8.131.52, request: “POST /xmlrpc.php HTTP/1.1”, upstream: “fastcgi://unix:/var/run/php5-fpm.sock:”, host: “184.108.40.206”
…which I assume are related. Any ideas what’s going on here and how to fix it?
