Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php
for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php
for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
I can't do anything w/o a coredump.
You should check your ulimits configuration, the directory where FPM children
process are in (chdir FPM parameter), the rights of this directory and ensure
rlimit_core FPM parameter is not set (to use default ulimit values).

Description:
------------
I use an nginx + php-fpm installation. Php-fpm is installed form ports.
The problem is, that php-fpm children sometimes (not always) got signal 11 when the master process
attempts to rotate em:
[10-Apr-2012 20:46:30.072189] DEBUG: pid 14165, fpm_got_signal(), line 72: received SIGCHLD
[10-Apr-2012 20:46:30.072278] WARNING: pid 14165, fpm_children_bury(), line 252: [pool www] child
14590 exited on signal 11 (SIGSEGV) after 121.434207 seconds from start
Seems like this doesn't affect the production process, but anyway this bothers me and I think
you will agree that bugs should be attempted to be fixed.
I would be really glad to present you a backtrace, but unfortunately I don't see any corefiles
anywhere. Core dumps are enabled, even for suid/gid processes:
# sysctl -a | grep core
kern.corefile: %N.core
kern.nodump_coredump: 0
kern.coredump: 1
kern.sugid_coredump: 1
debug.elf64_legacy_coredump: 0
debug.ncores: 5
debug.elf32_legacy_coredump: 0
But still no cores.
Test script:

I don't think this is relatred to some particular script.
