If you look at the attached image, you will see that the supplier replica (122) is at "10/28/2017 23:37:06”. The supplier column correctly lists the supplier. But the Supplier Max CSN column doesn’t use the max CSN in the master header (10/28/2017 23:37:06). Instead it uses the Max CSN of the supplier local to the consumer? According to the screenshot, the lag is 0 secs. But the lag is actually 10/28/2017 23:37:06 minus 10/27/2017 21:54:14? Thanks, Sergei <Screen Shot 2017-10-29 at 10.26.42 AM.png>
