children)
Status: Analyzed

Package: FPM related

New Comment:
I've submitted a new revision of the patch which patch fpm_events so that it
won't
trigger an FD event if it's been triggered less than 500µs.
See if it corrects the previous bug.
Please remember to clean your source tree (make clean) before compiling
otherwise
you may experience segfault or strange behaviors.

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
