DArray: Memory cannot GC when the variables are reassigned, causing `Out of Memory` error or halting problem

MWE: ```jl using DistributedNext addprocs(8) @everywhere using Dagger N = 1024 a = zeros(N,N,N); # 8GB b = DArray(a); #! Repeat this, and the CPU memory keeps growing until the Julia session is killed by system ``` I have tried the followings but the memory occupation cannot decrease: ```jl b = nothing; GC.gc() @everywhere GC.gc() ``` Is there a way to reuse or manually release the memory of `DArray`? I cannot find any solution in the documentation or github issues.
