I look forward to seeing fixes in 4.3.5. David P.S. Limiting the frequency of pings to the same target makes perfect sense to me; perhaps an easy solution would be to perform the same recently-used check before deciding to reclaim a particular abandoned lease in the first place (i.e. if the lease was marked abandoned so recently that we wouldn't be willing to ping it again yet, then we don't attempt to reclaim it at all).
