too dense mesh deteriorates the simulation

I'm using pimpleFoam to simulate the flow around a circular cylinder. I found that many times that if a dense mesh is used for a low Reynolds number simulation, say Re=100, the simulation is not physically correct(in terms of the drag or lift force coefficients). However, if I maintain the same mesh and raise the reynolds number to like 1000, the simulation seems to go well.
does someone else also have the same experience with me?
