ParticleSystem particles do not disappear when ParticleSystem is run for a long time

Greetings. I have an issue where the ParticleSystem's emitted particles simply do not disappear if it is run for a very long time (24hrs+). The project I'm working on requires that a scene is run for several days, which is why this problem occurs. I suspect there is some kind of overflow related to the time elapsed in the scene or something, but I can't really know for sure.

Does anyone know the solution for this? I'm currently testing out running PS.Clear() followed by PS.Play() to attempt to reset it, but I won't know if it works before it has been a few days.
