I tried already and here is the error message :
WARNING: MaxClients of 512 exceeds ServerLimit value of 256 servers,
lowering MaxClients to 256. To increase, please see the ServerLimit
directive.
Any ideas why ?
I was wondering if I put it at the right place but I did like you, so there is
no reason. I heard it was hardcoded during the compilation
I also did some test with 512, it *seems* to be slower :-/
Perhaps i'm not tunning the best parameter for my needs ?

I had any, I guess I pasted that from the previous server during the
migration....
