Description:
------------
I ran some load tests on a virtual machine which has 16GB ram and four 8Ghz VCores. 

The tests were run using JMeter.
When ~300 simultaneous connections (10 request loop per connection) to FPM exist (through NGinx), The master process crashes and I get 502 errors. The remaining child processes continue executing their scripts then terminate.

I use a static pool configuration, and no matter what the child processes number is, it crashes.

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 am unable to reproduce the crash for now, so I cannot provide dumps or a backtrace. If it happens again, though, I'll do.

Thanks for your time.
