It is indeed a bug with fluids involving particles birthing and dying. As previously mentioned, opacity ramps based upon lifespan will solve the problem.

@TwelfthToaster It has ramp. It wouldn't solve it. It's old bug with fluids opacity. Someone addressed it on cgtalk and Duncan confirmed.

@Htogrom the ramp needs to have same flow its basically running on off on off, but if you throw a black just at the top before the white, the transition should be smoother therefore no popping.

@JlNGLEZ Please read the rest of the comments. As I mentioned It is a bug, addressed on Cgtalk forums. No matter what you do to the ramp, when fluid is right before dying, it pops out.

Maybe that was fixed in maya2011, didn't tried it yet.
