In fact i'm a new sysadmin in this compagny and they give me this problem t=
o=20
solve. Apparently this name server was working fine since long time (1-2=20
years) and since september this trouble have began.
I have look to the graph (we graph all), and this "20%" of nxdomain are=20
"normal", we have this % since several months.
Still with graph we do not see high load, or low memory.
