[mrtg] Re: MRTG show drops regularly

[Zeeshan Ahmed]

Same thinng happend with me and i was not able to fix the problem and then i
just tested running a new configuration file and using new config file i
didnt see any drops in graps,so you might have to make new config file.but
in this case you will loss the the previous data.
