What I see is that replication actually occurs; what really fails is:

1) reading the contextCSN from ""

2) writing the contextCSN to ""

This is totally undesirable.  Probably, having context info in a subentry
of the context entry, as it was initially, would not have caused the
problem.

I suggest this issue is noted in the documentation of the "push" syncrepl.
