I am currently getting an empty solution for the query above from both our endpoint and the WDQS endpoint:
[1] https://tinyurl.com/y2t5nwc9 -- results page
[2] https://tinyurl.com/y66n9bk5 -- query editor page
[3] https://tinyurl.com/yxo5kr4w -- WDQS endpoint
What did I miss?

What was the problem query? I ask because I would like to try it against our Wikidata endpoint at: https://wikidata.demo.openlinksw.com/sparql . We have an "Anytime Query" feature designed for these kinds of problems, hence the vested interest in these kinds of problem queries. -- Regards, Kingsley Idehen Founder & CEO OpenLink Software Home Page: http://www.openlinksw.com Community Support: https://community.openlinksw.com Weblogs (Blogs): Company Blog: https://medium.com/openlink-software-blog Virtuoso Blog: https://medium.com/virtuoso-blog Data Access Drivers Blog: https://medium.com/openlink-odbc-jdbc-ado-net-data-access-drivers Personal Weblogs (Blogs): Medium Blog: https://medium.com/@kidehen Legacy Blogs: http://www.openlinksw.com/blog/~kidehen/ http://kidehen.blogspot.com Profile Pages: Pinterest: https://www.pinterest.com/kidehen/ Quora: https://www.quora.com/profile/Kingsley-Uyi-Idehen Twitter: https://twitter.com/kidehen Google+: https://plus.google.com/+KingsleyIdehen/about LinkedIn: http://www.linkedin.com/in/kidehen Web Identities (WebID): Personal: http://kingsley.idehen.net/public_home/kidehen/profile.ttl#i : http://id.myopenlink.net/DAV/home/KingsleyUyiIdehen/Public/kingsley.ttl#this _______________________________________________ Wikidata mailing list Wikidata@lists.wikimedia.org <mailto:Wikidata@lists.wikimedia.org> https://lists.wikimedia.org/mailman/listinfo/wikidata -- Hi, do you like citation networks?

Hi,
Thanks for looking into this, note that we don't have yet a reproducible scenario to trigger the dead-lock that caused the incident. Given the strong relations (timeline) of the suspected activity and the incident we are investigating into this direction but the query mentioned here is not sufficient to bring blazegraph down, there are probably other conditions (writes, query load) that we yet need to identify.
