It would help to have a better description of the symptoms of the failure.
Can you describe what you mean by "water molecules come out of the cap"? Are
there any messages when the simulation stops?

This is confusing: water caps can only be used for non-periodic simulations.
It doesn't make sense to have a water cap in a periodic simulation. Is that
what you are trying to do?
