Untracked Memory

Hello all! I had a question on what exactly could be causing UntrackedMemory. On the client, it is a perfect 0 and there seems to be no memory leaks. However, on the ServerSide, it is way higher and staying at around ~150 - 250MB, then spiking and then falling back down only to increase in memory the longer it stays up. I was wondering if this should be a concern, and if it is then what could I do to help reduce it or if my scripting is faulty? Thank you so much!
