Problems with check_rrd_bw.sh plugin

[danilo.perdomo at inter.com.ve]

Hi all! 

I've been having problems with the Nagios plugin check_rrd_bw.sh. It 
checks the traffic of some of my links in a
RRD format. The thing is that every now and then i get some results that 
are incorrect  (-2147 Mbps) and affects
the alert notifications in case some of the links are in a critical value.
Has anyone used the plugin? any help?

The output in Nagios:

OK - Current BW in: -2147Mbps 

Here's the plugin: http://pastebin.com/m27ba16ad

Thanks!
