Weston Pace commented on ARROW-18240:
-------------------------------------
Threads #3 and #6 are suspicious. Generally a CPU thread pool thread should
not be in a blocked state. Yet both are waiting on futures. That should only
happen on user threads (or possibly I/O threads).
> [R] head() is crashing on some nightly builds
