Interface fast flap (or a single up/down) somethimes mark OSPF routes as inactive

Bugs

Hi,

Sometimes, when quick flapping occur on a interface (this case 10G form Intel/HP with ixgbe/qlcnic), OSPF go down and UP fast and then some routes stale as inactive. Traffic stops and even another route is available (witch higger cost) traffic doesn’t work(this is OK because OSPF costs). The problem is witch routes marked as inactive.
The server is a ProLiant DL360e Gen8 with Intel 82599ES and Qlogic cLOM8214

luis@VyOS-1:~$ show ip route ospf | grep inac
O 10.5.50.253/32 [110/52] via 10.254.255.2, eth4 inactive, 00:04:10

O 10.255.10.41/32 [110/52] via 10.254.255.2, eth4 inactive, 00:04:10

To solve, I only need to disable/enable this interface.

Looking for something like this, I only found these below, but are not the same case:

Maybe related with a blackhole route? (not sure)
