Those pins are logic input pins, so they consume in miliamps range. If the resistance is high, they consume almost nothing, and that is how it should be. The MS pins have pulldowns like 100k. So the range of 100k-50k is ok. For sleep and reset also at least in kohms range. The range like 40-100ohms thats probably not ok. For 5v, that points at a consumption like 50-125mA which is well outside of what a logic pin should be like.
