[Bug 723480] Re: php5-fpm uses too high value for pm.max_children by default

[Clint Byrum]

Hi Marco, thanks for taking the time to file this bug report.

There's a basic assumption I think that can be made, that servers have
at least 1GB of virtual memory (not physical). 6GB, however, is
excessive. Given that, I'm marking this bug as Confirmed. We'll need to
open this discussion up with Debian before we can consider it Triaged.

Given the assumption of virtual memory, I think 6 would be a reasonable
default, as this would leave 256MB for other daemons and FS cache, and
only begin swapping when memory pressure is extreme. Ideally people
would write PHP scripts that don't leak so badly as to use 128MB of RAM.

Since this one is subjective, I am setting the Importance to Low. I
think the importance is still somewhat open to discussion, but we
definitely should lower this default no matter what.

** Changed in: php5 (Ubuntu)
