Description (partial)

ISSU aborted during load phase due to OSPF did not declare ready in time as OSPF SPF milestone not completed.

    Milestone                       | Start Time          |  End Time  
ospf (1029) on 0/RP1/CPU0 (9/10 done)
    OSPF SPF is done*               | Apr  6 13:39:52.826 | -

SPF not done hence milestone complete notification not sent from OSPF to ISSU infra and that's why this got broken

Only under the specific condition when there is exact LSA to be processed in External LSA Q or Summary LSA Q is the same exactly as SPF LSA processing quantum value defined (here quantum value 150) this issue got hit
