strange problem sysctl.conf
I have a problem with my server :
in the last days the server is slow so I remembered that I have some statement in my sysctl.conf to limit trafic
so i edited the sysctl.conf and made some changes and rebooted the server
but the server didnt started 
i ordred a kvm and entred to my server and i restored the sysctl.conf to default ( system default ) and rebooted the server but it didnt start
so I think that the problem isnt in the sysctl.conf
so whats the problem is ?
note : the server has not rebooted for a month
