I had seen that in fact, but similarly my override-xml file did nothing. I managed to solve the problem by decompressing the blazegraph-service.war file, editing the web.xml file directly, and recompressing.
I am trying to run a big query on a Wikidata instance, but the query fails everytime after exactly 10 minutes. The query and error output are included in the attached image. The only parameters that I have changed are the java and native heap sizes (both 64g) and the analyticMaxMemoryPerQuery, which I have set to 0 so that it is unbounded. I have not edited any timeout parameters. Is there such a parameter that defaults to timing out after 10 minutes? If so, how can I change it? And if not, how else...
