Yes - know limitation.

btw, I tried this:
bin/tdbstats --set tdb:unionDefaultGraph=true --loc /tmp/test-indexes
...and it also generated "empty" results.
This should help:
tdbstats --graph=URI ....
It may work on "urn:x-arq:UnionGraph"

Is that the expected behaviour?

Hi,
I'm having problems generating TDB stats for some data that I've
indexed using tdbloader2 in Apache 2.7.4.
The data is a copy of the Ordnance Survey data available from here:
http://archive.org/download/kasabi/ordnance-survey-linked-data.gz
From the Apache 2.7.4 directory I run tdbloader2 asking it to index
the unzipped nquads file.
The indexer runs fine and I can query the data in fuseki without
problem. However if I run
bin/tdbstats --loc /path/to/indexes
I get:
(stats
(meta
(timestamp
"2012-11-06T16:16:05.798+00:00"^^<http://www.w3.org/2001/XMLSchema#dateTime>)
(run@ "2012/11/06 16:16:05 GMT")
(count 0))
(other 0))
I also extracted the first 1m quads (head -n1000000) into a separate
file and indexed that. The result is the same. Indexes appear to be
created OK but tdbstats still produces an empty count.
I'm using Ubuntu on a 32bit system.
Any ideas?
Cheers,
L.
