Some further testing: I think server is fine since telnet makes a
connection and ngrep says for telnet
interface: lo (127.0.0.0/255.0.0.0)
filter: (ip or ip6) and ( port 1066 )
But client is dead, no trace in ngrep and no error. It just hangs for
./dcmd ls --server http://localhost:1066
or
./dcmd ls --server donaldduck
--help doesn't mention any way to get more debug info for the client. I
guess there isn't any hidden debug switch?

While testing RDF Delta, I'm following the instructions and have
server running:
java -jar delta-server.jar --mem
[2019-10-21 13:20:00] Delta INFO Provider: mem
[2019-10-21 13:20:00] Config INFO Delta Server port=1066
[2019-10-21 13:20:00] Delta INFO RDF Delta 0.8.0
2019-10-12T08:58:34+0000
[2019-10-21 13:20:00] Delta INFO No data sources
Connecting to it succeeded once
./dcmd ls --server http://localhost:1066/
-- No logs --
But never since. Restarting server doesn't help and the connection
just hangs, no timeout or any error.
Any idea what could cause that?
Works for me.
Are you sure the server processed isn't suspended? It does not run in
the background unless you put it in the background. Just suspending it
would behave much as you describe.

RDF Delta [1] does this for a dataset (as "dataset" is the unit of
transactions, it is all related changes).
But if it is one graph out of a dataset, then it is more complicated
- any update may change both local and replicated graphs together.
You could have a special dataset that picks one the one graph to
replicated as a layer over the storage dataset and use Delta for that.
The other approach is if the updates to the replicated graph are
separate from the other graphs in which case, simply sending the
changes to each server may be a workable approach for you.

We have 3 servers each running an instance of Jena/Fuseki, one
server being the master. All servers have one graph in common, but
they contain other graphs too which contain server specific stuff
and are not to be synced.
Is there a tool that helps to sync the graph on other servers from
master automatically?
