OK is 32768 is ok ? 32768/256=128 max files by backend ...
I don't know (and would like to know if possible) what is the
implication of this file-max for my server ?
What is the maximimum size of the file max for a linux ? In fact that
depends of what ? ;)

I understand what you mean ... but you can see my Apache log file of
today ...

[Wed Dec 13 12:16:14 2000] [info] server seems busy, (you may need to
increase StartServers, or Min/MaxSpareServers), spawning 8 children,
there are 0 idle, and 39 total children
[Wed Dec 13 12:16:15 2000] [info] server seems busy, (you may need to
increase StartServers, or Min/MaxSpareServers), spawning 16 children,
there are 0 idle, and 47 total children
[Wed Dec 13 12:16:16 2000] [info] server seems busy, (you may need to
increase StartServers, or Min/MaxSpareServers), spawning 32 children,
there are 12 idle, and 63 total children
[Wed Dec 13 12:16:17 2000] [info] server seems busy, (you may need to
increase StartServers, or Min/MaxSpareServers), spawning 32 children,
there are 45 idle, and 95 total children

What can I do ... and why I'm in this case ?

Many thanks per advance for your help !
