[Bug 1288129] [NEW] reload -> unable to read what child say: Bad file descriptor (9)

[Florian Engelmann]

Public bug reported:

OS: Ubuntu 12.04.2 LTS
Kernel: 3.5.0-43-generic #66~precise1-Ubuntu x86_64 GNU/Linux
php5-fpm:  5.3.10-1ubuntu3.10

Sometimes php-fpm crashes with:

[04-Mar-2014 06:47:45] NOTICE: Finishing ...
[04-Mar-2014 06:47:45] ERROR: unable to read what child say: Bad file descriptor (9)

[04-Mar-2014 06:47:45] NOTICE: exiting, bye-bye!

"service php5-fpm reload" also causes a crash (sometimes):
