After quite a bit of testing and some patches the problem was resolved...

thank you to Vigneswaran for the feedback and testing.

The problem was happening when an interface was going down. This
removed all existing links of this interface directly, which in turn
prevented the node from announcing them as "lost" is the next
Hellos... which made the neighbors NOT throwing their 2-hop database
entries away.
