Nginx and CSF Error Email

Hello,

I have two linodes. One in Tokyo and one in London. I installed cpanel on both.

Now I also installed nginx and ConfigServer Security & Firewall on both wit exactly the same commands.

On the Tokyo server evrything works fine. But the London server keeps sending Email every 5 minutes like: FAILED: lfd on xxxxxx.members.linode.com (xxx.xx.xxx.xx) for both nginx and ConfigServer Security & Firewall.

Hope somebody can help me.

Thanks,

Luca
