      Description

      Wikidata Query Service updater periodically gets HTTP errors which leave this in the log:

      Mar 01 20:37:55 wdqs1003 bash[13375]: 2017-03-01 20:37:55.252:WARN:oejh.HttpParser:qtp1531448569-696: badMessage: java.lang.IllegalStateException: too much data after closed for HttpChannelOverHttp@4a9dd88d{r=2,c=false,a=IDLE,uri=-}
      

      This fails the update HTTP query, which updater retries and it works OK then. So the query content itself isn't a problem. But I'm not sure what is - would appreciate any pointers as to what could be the issue. It's not a timeout issue as by logging timestamps it happens immediately after the query is issued, e.g.:

      Mar 01 20:42:27 wdqs1003 bash[27086]: 20:42:27.469 [main] INFO  o.w.q.r.t.change.RecentChangesPoller - Got 381 changes, from Q26216198@458860704@20170301182219|486710007 to Q26178350@458861191@20170301182311|486710495

      Mar 01 20:42:27 wdqs1003 bash[27086]: 20:42:27.473 [main] INFO  o.w.query.rdf.tool.rdf.RdfRepository - HTTP request for query failed: org.apache.http.NoHttpResponseException: localhost:9999 failed to respond, retrying in 1018 ms
      

      i.e. error is issued immediately after the query is sent.
