Administrative task are sensitive and some side effect can impact
replication. When you reinit rh5->rh1, then rh1 can still replicates to
dr-rh1. However a side effect of reinit is that it clears the changelog
of rh1. So if dr-rh1 is late, then rh1 having lost history of old
updates (changelog reset) is able to connect to dr-rh1 but is no longer
able to find in its cleared changelog, the old update it should start
replication from.

The workaround is to give rh5 a chance to directly update dr-rh1.
