Not entirely sure, but my last two queries (which shouldn't take that long) are still "running"
Topic on Talk:Quarry
(seems okay now, might just be what Quarry is like)
A few seem to be hung like Quarry:query/11034 . I noticed that such exciting queries like "SELECT * FROM page" or similar tend to hang. I don't know why just these often not get killed automatically. @YuviPanda, any idea?
One more example https://quarry.wmflabs.org/query/14329
