OSPF and mass route deletion

OSPF doesn't delete "routes", it sends LSAs.
It seems that you are redistributing a lot of single IP addresses in OSPF (as external routes). So there's one LSA type 5 for each single redistributed /32.

OSPF is not the proper choice for this usecase, and it's not a Quagga or BIRD issue.
BGP is the protocol to use for such cases. Many routes, few messages, scalability.
