z/OS OMPROUTE OSPF support for LSA type 7

Some sort of support required for LSA type 7 when dealing with Cisco ACI fabric networking. Our OSPF implementation with VIPA allows our systems to move between sites seamlessly but with the new ACI fabric we can't define every host as "totally stubby" (it's not tolerated) and then we get these messages when the OSPF area has many hosts in it.

Actually we'd be fine with changing the code to just post one message about this and then totally ignoring LSA type 7. We are mostly concerned with the continuous resources being wasted generating the messages about "ignoring LSA type 7" and filling SMF.

    I assume the message in question is EZZ7924I, is that correct? Also we don't want to lose the information completely, but I can see the flooding of repetitive messages being a problem. Would it be acceptable to show the message once from each neighbor over a time interval? In other words, the first time we get one of these LSAs from a neighbor we would put the message out and then not show it again from that neighbor for, say 5 minutes. Then after 5 minutes show it again, and suppress for the next 5 minutes, etc. Would that reduce the vast majority of the messages and relieve your issue?
