Definitely. Since it happens fairly predictably, you should also be
able to set the load-interval to 30 on the interfaces connecting to
those neighbours and check if there's a momentary increase of traffic
on those interfaces when the problem occurs.

Can you route around the problem while you troublshoot? (maybe force
a high ip ospf cost on the L3 interfaces)
