rocket exercise - particle system issue

Hey all, 

So I've done the rocket tutorial and used cycles with nodes for the exhaust animation and it is working fine in the timeline on preview mode, but when I render it somehow i've got a few frames where the velocity of the exhaust seem to revert.  I checked, those values are not keyframed (only the lifetime is.).

Also there is some jittering at start of the animation.

Not  sure how I can troubleshoot this as in the viewport it works perfectly.  Any idea?
