I'm trying to migrate my platform from lighttpd and spawn-fcgi to
nginx and php-fpm. I've setup a very basic config on nginx and php-fpm
my server handles about 120r/s all php calls I've been trying to use a
unix socket because i heard that they are faster than using the
loopback device. I keep getting (11: Resource temporarily unavailable)
while connecting to upstream as soon as i turn on the traffic to it.
the load on the server is about 1 and its an 8 core machine that under
lighttpd responds fine at a load of 9. memory is not an issue as i
only use about 3gb of the 8 it has available.
on lighttpd and spawn i also use unix sockets and spawn cgi

fastcgi.server = ( ".php" =>
( "localhost" =>
(
"socket" => "/tmp/php-fastcgi" +
PID + ".socket",
"bin-path" => "/usr/bin/php-cgi",
"max-procs" => 50,
"min-procs" => 5,
"bin-environment" => (
"PHP_FCGI_CHILDREN" => "2",
"PHP_FCGI_MAX_REQUESTS" =>
"15000")
)
)
)


Here are my configs

I am fighting a cold and can't seem to get a handle on it and can't
concentrate but a couple things I notice...

<value name="max_children">200</value> = PHP_FCGI_CHILDREN
i'd set that to 50, not 200

<value name="max_requests">1500</value> = PHP_FCGI_MAX_REQUESTS
you used to have 15000. i'd set it to 500

I figured out that the -1 value of the backlog that supposedly should
take the somaxconn value from the sysctl doesnt work. If i increase
the backlog on the fpm config to 4096 the errors disappear. my sysctl
value for somaxconn was 8192

So that sounds like a bug then?

"backlog with -1 is supposed to take the sysctl value but does not" ?
