Log GeoIP

Hello everyone,

I install the GeoIP for my Nginx server and it's operational and it's work nicely.

But in the log of nginx i have this error : [error] 864283#864283: *1 cycle while evaluating variable "denied_ip", client: ******

Someone can help me to explain this and result this error ?

P/s: the setting of GeoIP it's standard setting

Thanks you
