[mrtg] Problem with snmpd/mrtg interface (possibly)

[Moriarty]

Hi,

I recently compiled a new kernel for FreeBSD 4.7 stable and ever since i
havent been able to get mrtg working. It generates the stats for device xl0
(10.4.3.10) (3com 905c nic) perfectly, which is first in the config, but the
mrtg process breaks with the below error message when trying to make the
stats for the wireless device wi0 (10.4.1.20) (Avaya 802.11b nic). I had
this setup running fine until an unrelated program needed changes to the
kernel. Anyhow, heres the error generated when i run mrtg..
