Description:
------------
idle and total processes number is very big:

pool:                 www-production
process manager:      dynamic
start time:           11/Aug/2011:21:59:29 +0800
start since:          1019087
accepted conn:        21192088
listen queue:         0
max listen queue:     0
listen queue len:     0
idle processes:       8915
active processes:     2
total processes:      8917
max active processes: 177
max children reached: 4

my fpm config:

pm = dynamic
pm.max_children = 192
pm.start_servers = 64
pm.min_spare_servers = 48
pm.max_spare_servers = 96
pm.max_requests = 512

process manager:      dynamic
start time:           11/Aug/2011:22:03:52 +0800
start since:          1075150
accepted conn:        23790807

idle processes:       419
active processes:     3

the idle processes is 419, but my pm.max_children = 192

Hi, I'm having the same problem.

PHP Version: 5.3.8
OS: Ubuntu 10.04.3 LTS
Compile options: './configure' '--enable-fpm' '--with-mcrypt' '--with-zlib' '--
enable-mbstring' '--with-openssl' '--with-mysql=mysqlnd' 
'--with-mysql-sock' '--with-pdo-mysql=mysqlnd' '--with-gd' '--with-jpeg-
dir=/usr/lib' '--enable-gd-native-ttf' '--with-
curl=/usr/include/curl'

It seems that the number of idle processes rises until php-fpm is restarted, you 
can see the behavior from this munin graph:

Let me know if you need any additional info in order to debug this.

Thanks,
Andrea

It is a guess that the problem is caused by this code (the fragment of fpm_process_ctl.c line 339):

/* update status structure for all PMs */
if (wp->listen_address_domain == FPM_AF_INET) {
    if (0 > fpm_socket_get_listening_queue(wp->listening_socket, &cur_lq, NULL)) {
        cur_lq = 0;
#if 0
       } else {
            if (cur_lq > 0) {
                if (!wp->warn_lq) {
                    zlog(ZLOG_WARNING, "[pool %s] listening queue is not empty, #%d requests are waiting to be served, consider raising pm.max_children setting (%d)", wp->config->name, cur_lq, wp->config->pm_max_children);
                    wp->warn_lq = 1;
                }
            } else {
                wp->warn_lq = 0;
            }
#endif
    }
    fpm_scoreboard_update(idle, active, cur_lq, -1, -1, -1,FPM_SCOREBOARD_ACTION_SET, wp->scoreboard);
}
---
As you can see the fpm_scoreboard_update is called only when the php-fpm listens on AF_INET, but not on the unix sockets.
It is is a guess, I didn't test it, but this code is suspicious.

Thanks, simply moving the fpm_scoreboard_update line outside that if did the 
trick.

I hope someone will commit a fix into the svn.
