When I created the first CBT based replication for a number of VMs, the log file showed CBT 1 for each of these VMs when executing the replication with option --replica=cbt.
On subsequent runs, I would expect that CBT is always incremented by 1 so that we have CBT 2, then CBT 3 and so on.
However, what I realized was that CBT was increased by 4 for each run, so the sequence was CBT 1, CBT 5, CBT 9, CBT 13.
Is there anythig I have to worry because of this?
I made a simple test where I just executed another replication run right after having finished the previous one. So I cannot image that another process was interfering in between that caused an extra increment.
