Hi Jeorg,

 Starting with the 'obvious' is always a good idea :)

 What other events are taking place on the router at the same time of
(or prior to) relatively high loads? Any link flaps, neighborships
going down/up etc?

 Also, you may check whether this is a particular issue (every n time)
or not to have a better idea.
