hi all,
I see this Exception with a very big SPARQL select query (182825 bytes)
on a TDB with jena-fuseki-1.0.2-20140315.080253-36. After an upgrade to
jena-fuseki-1.1.1, the problem is still there. The query used to work before
but took very long (ca. 900s).
What does the error mean?
The client went away before the query results had all been sent.
There can be various reasons for this :
Client has actually gone away
Some intermediary (load balancers, reverse proxy, proxy/client-end)
timed out. (Not the query timeout).
Is the request a lot of work before any results (i.e. idle connection)?
Is my TDB corrupted?
No.
