sysctl.conf settings

[Bulent Tekcan]

Hello,

I have a very high traffic web site and server. Today I saw some error while reload sysctl.conf . I'm using these settings since 4 year w/o any problem. But I think some line not supported new kernel ? Any idea about some line warn ....... is an unknown key ?

Maybe problem come from my ethernet port ? Because my port address is em1 not eht0

What kernel are you running?

 

[sparek-3]

And is Kernelcare even installed on this server?

kcarectl -i
