Andi, with regard to your request I will need some help as I don't know what
you are asking me to do.
Could you try the following: carry out those actions outside of
Fuseki/Joseki without inference. It'll help pin down what's happening.
You can use Fuseki as a standalong TDB installation (the server jar has
all the classes you need in it)
From the store at (1), load the new data either using arq.update (i.e.
applied the SPARQL Update.
Issue a query.
My dataset in test.ttl originally looks as follows
urcscl003: tdbdump --loc=/tmp/TDB
<http://www.example.org/e1> <http://www.w3.org/2000/01/rdf-schema#label>
"testunit" .
<http://www.example.org/e1> <http://purl.org/dc/elements/1.1#author> "mgi" .
<http://www.example.org/e1> <http://purl.org/dc/elements/1.1#date>
"12/13/2011" .
After updating it with Fuskei as configured below - note that it does not
matter whether I updated into service1 using #inf or service2 using #tdb -
Are you starting and stopping Fuseki at this point?
Specifically, is it stopped by the time the second tdbdump is run?
Your setup has the feature that you're using graphs in TDB in a general
dataset. It maybe the sync() from Fuseki is not getting to storage
properly s that's quite a complicated setup.
What happnes if you use:
<#tdb> rdf:type tdb:DatasetTDB ;
tdb:location "/tmp/TDB" ;
.
This directly connects service1<#tdb> to the data storage.
but you must stop running Fuseki before the second tdbdump else it may
see a partially written database. Some situations may thne corrupt the
node table.
Current versions of Fuseki (you have one from september and the snapshot
repo has moved:)

Sorry - you've hit things during our transition to Apache
