[mrtg] Threshold Error

I believe this is just the resulting erring when you try and poll an
interface that is in a down state. Am I correct in assuming you only get
these errors when you shut the interface down?

Subject: [mrtg] Threshold Error

I have decided to upgrade my mrtg system. I am building a whole new
machine from scratch and not using any of my old configs.

I ran cfgmaker against one of my switches to build a base config. I then
added a threshold on one of the ports. I shut the port down to test the
threshold. When the minimum threshold is reached I get an e-mail
notifying me of the issue. I also get another the cron daemon. It
contains the following error.

Use of uninitialized value in join or string at /usr/local/bin/mrtg line
Use of uninitialized value in system at /usr/local/bin/mrtg line 1971.
Can't exec "": No such file or directory at /usr/local/bin/mrtg line

I am unable to find any solutions on google. Does anyone have a perl of
wisdom to share on this issue.
