This looks related to BLZG-1418 (issue opened by @Smalyshev himself a couple years ago). It looks like a case of normal termination once a query has been canceled (looking at BLZG-1418 and the code in AbstractRunningQuery). This looks more like a too eager exception handler in ChunkedRunningQuery than a real issue.
