Hm .. i can only see tons of:
20983 poll([{fd=4, events=POLLIN}], 1, 108) = 0 (Timeout)
20983 clock_gettime(CLOCK_MONOTONIC, {4578918, 852647570}) = 0
20983 clock_gettime(CLOCK_MONOTONIC, {4578918, 852702140}) = 0
20983 clock_gettime(CLOCK_MONOTONIC, {4578918, 852754708}) = 0
20983 clock_gettime(CLOCK_MONOTONIC, {4578918, 852807040}) = 0
20983 poll([{fd=4, events=POLLIN}], 1, 130) = 0 (Timeout)
20983 clock_gettime(CLOCK_MONOTONIC, {4578918, 983213866}) = 0
20983 clock_gettime(CLOCK_MONOTONIC, {4578918, 983267442}) = 0
20983 clock_gettime(CLOCK_MONOTONIC, {4578918, 983323753}) = 0
20983 clock_gettime(CLOCK_MONOTONIC, {4578918, 983368483}) = 0
and then thousands of:
20983 munmap(0xae151000, 1040) = 0
20983 munmap(0xae150000, 1040) = 0
20983 munmap(0xae14f000, 1040) = 0
20983 munmap(0xae14e000, 1040) = 0
20983 munmap(0xae14d000, 1040) = 0
The socket gets created here:
20983 socket(PF_FILE, SOCK_STREAM, 0) = 6
20983 setsockopt(6, SOL_SOCKET, SO_REUSEADDR, [1], 4) = 0
20983
unlink("/etc/httpd/fastcgi/dynamic/5-53LATEST-wordpressmit.imageupgrade2.domainfactory-kunde.de")
= -1 ENOENT (No such file or directory)
20983 umask(0111) = 027
20983 bind(6, {sa_family=AF_FILE,
path="/etc/httpd/fastcgi/dynamic/5-53LATEST-wordpressmit.imageupgrade2.domainfactory-kunde.de"},
110) = 0
20983 umask(027) = 0111
20983 listen(6, 128) = 0
When making an request nothing happens in the strace :-(

You can strace to see what happens:
set log_level to debug
set daemonize to no
then run something like
strace -f -s 1024 -o /tmp/php-fpm.strace.log /path/to/php-fpm

Hello,
i know, but when i make an request, no child gets spawned.
My PHP-FPM has more pools. Every pool is listening to an different socket.
The mod_fastcgi 2.4.6 is patched, that it connects to the socket for the domain.
Example:
Hostname: www.domain.com has PHP Version 5.3.6
FPM Config for Pool is:
[domain.com]
listen = /etc/httpd/fastcgi/5.3.6-domain.com
user = u12345
group = nobody
pm = ondemand
pm.process_idle_timeout = 10
pm.min_delay_between_fork = 10000
pm.max_children = 5
When now an request for www.domain.com to the apache arrives, the apache looks
in the ldap for the PHP Version, then mod_fastcgi searches for socket
/etc/httpd/fastcgi/5.3.6-www.domain.com, if not existent for
/etc/httpd/fastcgi/5.3.6-domain.com (snips www. ). Now Apache connects over
mod_fastcgi to the correct socket, but no child gets spawned with pm = ondemand
With dynamic and static all works fine.
Any suggestions ?
Greetings,
Daniel
