Well, after a day or so my lighttpd troubles reappeared. But this time, the lighttpd process would simply put out this:
|
1 2 3 4 |
(mod_fastcgi.c.2913) backend is overloaded; we'll disable it for 2 seconds and send the request to another backend instead: reconnects: 0 load: 131 (mod_fastcgi.c.2668) fcgi-server re-enabled: 0 /var/run/lighttpd/lighttpd-fastcgi-php-17242.socket (mod_fastcgi.c.2913) backend is overloaded; we'll disable it for 2 seconds and send the request to another backend instead: reconnects: 0 load: 131 (mod_fastcgi.c.2668) fcgi-server re-enabled: 0 /var/run/lighttpd/lighttpd-fastcgi-php-17242.socket |
And as the message says, PHP (or rather mod_fastcgi?) would simply stop to process requests. In the end, I tuned some of the lighttpd/mod_fastcgi parameters.

"max-procs" => 2 "idle-timeout" => 20, "socket" => "/tmp/php.socket-" + var.PID, "bin-path" => "/usr/bin/php-cgi", "bin-environment" => ( "PHP_FCGI_CHILDREN" => "6", "PHP_FCGI_MAX_REQUESTS" => "7000" ) |
Up till now (I made the change on July 14th), these changes seem to have fixed the issue, guess I’m still hoping (with the saying “Hope dies last” in mind) it’s gonna fix my problems once and for all.
