Hi,
Seems to be a bug in the global bandwidth settings. If you set them to kbit/s instead of mbit/s and use a value over 1000, then the mrtg service will only run for 10 seconds and quit. I’ve sent some diagnostics to Fulvio and he says he thinks he has it figured out and will fix soon. In the meantime, just use mbit/s and set it with a decimal like 1.344 as a solution.
Good luck,
Alan
