[Assaf Flatto]

Hello 

I am getting this error when trying to run Check_host_alive on some of my hosts configured in 
nagios .

I have 307 hosts in status "Up"  and 41 in status : "Pending"
when i try to force a host check i get the an error in the debug log .

nagios.debug :

I tried to google this and got some very confusing hits on code changes need to be done .

Can anyone explain in simple way how to fix this issue ?

Thanks
