My bad, I want to say that the checkpoint could not execute as expect because checkpoint time cost will enlarge. Consider case: 1 ANN + 1 SBN + 6 Observer, with configuration checkpoint every hour and `maxThreads=1` when checkpoint and fsimage file size is 100GB. The whole time cost could be like the following, 100GB*(1024MB/GB)/(100MB/s) * 8 =136min where 8 = 1 (dump) + 7(upload) Here 136min>60min, and checkpoint will postpone about 2 hours later which is not expect, right?
