@Massimo, I upgraded to 2.2.1 but memory problems are still there. I will
do some more testing.
Memory goes up +100Mb in less then a minute when I try to make a lot of
traffic (hitting Ctrl + R )
@Niphlod
This is the config part. I think values are default ones that come with
apache.
<IfModule mpm_worker_module>
StartServers 2
MinSpareThreads 25
MaxSpareThreads 75
ThreadLimit 64
ThreadsPerChild 25
MaxClients 150
MaxRequestsPerChild 0
</IfModule>
And htop is explained here:
http://serverfault.com/questions/24198/why-does-htop-show-lots-of-apache2-processes-by-ps-aux-doesnt?answertab=votes#tab-top
This is a list of apache modules:
