Hello,
Little feedback to this issue.
After 2 weeks running PHP-FPM using events.mechanism=poll, I did not experienced any segfault.
Seems that Rasmus was right.

Hello,
We have the same problem, with PHP 5.3.21 behind Nginx 1.2.6.
Happens, sometimes, at PHP-FPM reload, after updating the code.
We're running a Symfony web app, on Ubuntu 10.04 Lucid with home-made PHP packages.
Enabled modules
---------------
amqp 1.0.9
apc 3.1.9
curl 5.3.21
gd 5.3.21
geoip 1.0.8
igbinary 1.1.1
intl 5.3.21
memcached 2.1.0
mongo 1.3.0
mysql 5.3.21
pinba 1.1.0
redis 2.2.2
Have just modified FPM configuration to use 'poll' instead of default 'epoll'.
Will see what happen.
2 backtraces available (I can provide coredumps upon request)

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.
If you were able to give us a complete and detailed stack trace it would be
useful.
thx

Not sure. Many people out there run with epoll without problems.

We've been up and running for 24 hours with "events.mechanism = poll" and no
problems. Let's give it a couple of days to be sure this workaround works. Is this
issue specific to epoll and the way we have php-fpm configured (to use minimal
resources), or is this is a bug in php-fpm that can ultimately be fixed?
