re
I think my TDB is broken now. I got a memory error on
SELECT DISTINCT ?subj ?prop ?obj WHERE { GRAPH
<http://blogspace.com/swhack/chatlogs/rdflogs/2002-06-24.rdf> { ?subj ?prop
?obj } }
If I change -Xmx1G to -Xmx4G in bin/rdfserver, I do not get the memory error
but lots of errors of this kind:
11:18:04 INFO SPARQL :: Query: SELECT DISTINCT ?subj ?prop ?obj W

I have a recent backup of that TDB that has not been introduced to
