Hi Alexander,
When it "hung" did you try both HTTP and SQL(ie via isql ) connections to the
database as you may still be able to access the server to perform some
diagnostics as to the state of the machine ? I would also be interested to see
what was in the virtuoso.log file at that point also
Hi Hugh,
Yes, I have missed this point. But after running DB.DBA.RDF_GEO_FILL my
Virtuoso instance hanged. I couldn't stop it and after rebooting couldn't
start (had to restore from backup). I use High-CPU Medium instance for
storing LinkedGeoData Elements dataset, so may the lack of resources is
Hi Alexander,
Did you run the DB.DBA.RDF_GEO_FILL () procedure to create the geometry
data/predicates for the loaded LGD datasets as detailed at:
http://docs.openlinksw.com/virtuoso/rdfsparqlgeospat.html#rdfsparqlgeospatcrg
As if the "geometry" predicates do not exist, this would seem
Hi Hugh,
There wasn't any error. As there isn't "geometry" predicate at my instance,
Virtuoso doesn't find assertions with it and returns empty result set. Just
compare:
1. endpoint: lod.openlinksw.com/sparq
query: SELECT * WHERE {<

Hi Alexander,
Are the LGD queries that worked against the lod.openlinksw.com server giving a
specific error when you attempt to run against your EC2 AMI with the LGD
datasets loaded ? Also what is the exact version of the Virtuoso EC2 AMI, this
will be reported in the left frame of the conducto
Hi Kingsley,
Yes, geo capabilities work very well under Virtuoso Cloud Edition (good
performance was a great surprise after migrating from lod.openlinksw.com to
custom Amazon EC2 instance). Here I will quote the initial question to point
out the problem:
