Phil,

imagine some four routers dying or not answering queries,
you will see the poll script give you timeout after timeout
after timeout and with some 50 to 100 routers and the
respective interfaces you see mrtg choke badly, losing data.

You see, the poll script is doing one after the other,
mainly, so you wait too long and then the next run starts
and then something.

mrtg/rrd is not the tool of choice for accounting / billing
but nice enough for showing you 'backup' graphs for visitors
probably.

Hi.
