Irregular consumption of ram for gpe

when i load data 80gb into ram memory 50gb, ram memory for gpe used 30gb
when i upgrade ram to 90 gb the memory ram used increases to for gpe 60 gb, what makes this happen?

@maulcenter What’s the topology size? Could you run gstatusgraph? One possible reason is topology is 60GB and in 50GB machine it only loaded 30GB to memory.

@Jon_Herke this is the topology size

@maulcenter Are you still experiencing issues regarding the memory resizing?
