Jean-Marc Vanel commented on JENA-1553:
---------------------------------------
I also get this kind of error, on the main semantic-forms site.
It is running without problems since months.
It is often updated by users typing or download from the LOD.
It started by this stack on table view of all Event triples (after the SPARQL
query succeeded):

I just stopped the server.
The dump fails like this. A file is produced, however. Is it not complete and
terminates abruptly. The application view showing just the list of Events shows
that most are missing.

Then I tried to get my edits by this query:
{{cat user_jmvanel.rq}}
{{CONSTRUCT {}}
{{ ?s ?p ?o .}}
{{} WHERE {}}
{{ GRAPH <user:jmvanel> {}}
{{ ?s ?p ?o .}}
{{ }}}
{{}}}
{{java -cp $JARS tdb.tdbquery --loc=TDB --results=turtle --query
user_jmvanel.rq }}
I got several exceptions, and nothing was returned.

and two more like this.
Is there any chance to recover my data ?
