[Wikidata-bugs] [Maniphest] [Created] T206189: Set sensible thread limit to Blazegraph

TASK DESCRIPTION

We've had an incident where thread count in blazegraph rose up to 9K and clogged the system:

https://grafana.wikimedia.org/dashboard/db/wikidata-query-service?orgId=1&panelId=22&fullscreen&from=1538604561831&to=1538621054757

Maybe one thing we could do is to make a filter where if the count of active threads is too high, we just reject the new GET requests.
