[mrtg] Strange Problem with MRTG

[David Blevins]

Hello everyone.  There seems to be a lot of very good information and
knowledgeable people that are members here.  I have a problem that I really
need help with. Please take a look at my log files and hopefully you can
tell me if you have seen this error before.  My graphs turned blurry and
then my traffic flat-lined after a reboot.  Thanks for any help you can
give.
