It's likely out of memory issues with many many distinct values in an aggregated column, or with a very large join intermediate. The joins are now able to handle larger than RAM, and larger than RAM intermediates in a group by is on the roadmap!

Looking at the failed queries, yes, OOM might be one big factor due to aggregations (there is no join in these queries though).
