High memory usage

Hey I have a macro that runs 2 other macros in the same workbook. It runs 2 macros, saves the workbook, waits 10 minutes, runs again.

It starts using only about 4gb of ram (which is fine and expected) but I left it on for 3 days and when I came back it was using 12gb. Is there any way to get rid of this extra memory the program is using every time it loops?

I don’t think it has any leaks it just slowly adds up over days of continuous running but it needs to be on indefinitely.
