Thank you for the reminder, but I’m unclear on how to properly investigate and adjust the SPILL_BATCH_MEMORY_MARGIN variable.

I still don't think we should downgrade it to debug level, see #19846 (comment)

Perhaps @xudong963 can share some reproducer that triggers this warning, and we can figure out next how to suppress that specific case (maybe adjusting SPILL_BATCH_MEMORY_MARGIN would work)
