[phpa] Re: Page not found problem


Hey Nick,

Thank you for your answer. Here is my apache configuration:
KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 15
MinSpareServers 1
MaxSpareServers 50
StartServers 40
MaxClients 256
MaxRequestsPerChild 1000

So this seems to already answer your suggestion regarding max client (or is 
it still too high ?).
Upgrading php is an option. But we would have to test intensively our code 
before doing that.

What's your suggestion ?
