Hi there,

in the following request https://bugs.php.net/bug.php?id=54098, the
user ask to lower the FPM pm.max_children configuration item. As pm.*
configuration items are very specific to every situation (hardware,
code, # parallal requests, ...) there is no default value which suites
everyone.

I'd like to remove the default value from the php-fpm.conf file. After
that, with the default php-fpm.conf, php-fpm won't start until the
sysadmin specify what he wants. If package mainteners want the default
conf file to work, they can change it as they like.

What do you think ?

I tend to agree. A working out of the box configuration is no harder for
sysadmins needing to change it, and easier for developers to just install
and run..

Why not just set it low as he suggested? That's what Apache and most web
servers I know of does. Low is always safe and it means it works out of
the box.
