I haven't seen this but this was a side topic in one of our cases
3.5 years ago (OSPF no longer came up to Cisco after SW upgrade due
to how routerID was selected).
The side conversation was that a duplicate prefix (a loopback or ptp
most probably) in different parts of the network would cause somewhat
similar behaviour. This might be related.
