I can't tell from your description. Unless you use trjconv properly, VMD 
will show water molecules that cross the simulation cell boundaries with 
lines joining atoms on opposite sides of the simulation cell. If "become 
longer" means only a gradual and incremental increase, then you have a 
simulation problem.
