Re: Runaway network bandwith alarms after upgrade

[Paul Theodoropoulos]

Hi Martin,
Apologies for leaving that out - yes, all the other servers were Debian 
Wheezy, and all have been upgraded to Debian Jessie. All are running 
MOnit 5.19.

The server in question does get a lot of traffic, and notably 127.0.0.1 
has significant traffic - After two days uptime, there's 30 GiB of data 
through lo. However, even that doesn't add up to greater than 3GB/hour.
