okay, since this problem appears to be kind of common (and I don't have
an idea why it appears to begin with) I'll make this a configure switch
in the next versioin with the default being the `proc' part.. If anyone
trips over anything related I'd apprechiate a hint ;)

How's that? Such peaks usually happen when a counter gets reset (or an
overflow is not detected). The traffic counters are usually counted from
system startup. So `collectd' would have to influence the traffic
counters - which is shouldn't.. So, what environment does this problem
occur? The above configuration (64bit gentoo)?
