There are two issues i found while editing/rendering a particle-scene:
1st- an object appears on a position after i press render (sometimes)- its an object to visualize particles to render them on cycles.
This object is placed outside the camera-view and will be seen "sometimes" while rendering.
After rendering its still in the middle of my view- i saved the blend in this status.
2nd- i found out that a particle-system is more stable when i reduce the size under the physics-tab inside the particlesetup (i know substeps does not help everytime!).
When i make them smaller for the physics they are rendered smaller, too. So i´ve tryed to make them bigger by entering a
higher value in the render-tab inside the particlesetup. But when i change the particle-size for rendering, the particle-size for physics are changing, too.
Seems there are two the same fields?
I´ve packed the rendered animation for you in a rar (Jpeg Sequence). You will see issue 1 there when playing the animation.
The blend is there, too. And also 2 screenshots where you can see what im talking about.
Hope you accept Drop-Box links.
The files are here:

NOTE! : I´ve rendered the animation with 2.000.000 particles! For you i changed the amount to a smaller value.
