> Query was cancelled during external sort.
> Here is what happened:
> 1. Query got stuck in CANCELLATION_REQUESTED mode: ( queryid = 2967b65e-ea42-a736-9f5d-3513914ada88
)
> 2. On a forman node 6:0 (executing merge join) fragment kept running forever (see stack
below)

to give it a clue on what happened.
