[Virtuoso-devel] 500 errors again

[Sherman Monroe]

Hi Hugh,

The LOD server has been running smoothly all day. Then a few minutes ago, it
started giving 500 errors, and now seems to be stuck in this state (reboots
on my side aren't working).

Here is the API response containing the SPARQL that seemed to trigger the
errors:

<fct:sparql>    select distinct ?s8 as ?c1  where { ?s1
&lt;http://www.w3.org/2000/01/rdf-schema#label&gt; ?o1 . ?o1
