There should be no correlation between OSPF and pings. Can you post configs? Control plane policing on the 7750? CPM queuing?

Because the rapid command sends so fast, and the timeout is much longer than a normal response, the sequence of . vs ! is not accurate. Your 1st !.! could well be one of the 1st pings but it reports it occurring much later.
