Frequency with which PHP-FCGI restarts if it crashes?

Virtualmin
1

If php-fcgi crashes, it seems to restart itself after 10 minutes or so.

Is this a setting that can be adjusted? We have experienced crashes and the only way to get the site back online is to issue the following two commands or wait for PHP-FCGI to restart itself:

service php-fcgi-websitename-com restart
service nginx restart

When we look in /var/logs/virtualmin/websiteWithProblem_ca_error_log, we see the following errors:

2015/04/06 13:38:52 [error] 28320#0: *645985 connect() to unix:/var/php-nginx/138143759027147.sock/socket failed (11: Resource temporarily unavailable) while connecting to upstream, client: 99.234.44.39, server: www.websiteWithProblem.ca, request: “GET /page.html HTTP/1.1”, upstream: “fastcgi://unix:/var/php-nginx/138143759027147.sock/socket:”, host: “www.websiteWithProblem.ca”

any ideas? We’d ideally like this setting to check itself every 30 seconds or so instead of 10 minutes or whatever interval it actually is.

Howdy,

Hmm, it sounds like you may be running into some resource issues there.

What is the output of these commands:

free -m cat /proc/user_beancounters netstat -ntu | awk '{print $5}' | cut -d: -f1 | sort | uniq -c | sort -nr | head -10 dmesg | tail -30

I should probably mention this is on centos 6, nginx

Additionally, when php-fcgi crashes, the website is not accessible at all. Just a 502 bad gateway pops up.

any ideas?
