OnĀ SERVER-54874 we introduced an aggregation pipeline to refresh the catalog cache so that it reads config.collection and config.chunks at a same point-in-time in a single aggregation.
This pipeline can be optimized to avoid using intermediate arrays (that the $facet stage is generating). This intermediate arrays can hit the 100 MB limit and fail the aggregation.
