No. My system is a single protein with charged ligand associated with it. But why should box size shrink ? In solvated system it does not shrink. What effect vacuum could possibly have on it ?

If it's not constant volume then the simulation will change volume. Why should your charged proteins want to stay at the original distance from each other? It seems they want to collapse onto each other. You need to rethink your choice of ensemble.
