starting with the basics
Have you fully cached the fluid before sending to render??
Also, you should seperate your fluid from everything and have a seperate scene with just the fluid and or any holdout objects. No point in keeping all the particle / nparticle nodes if you just need a fluid render. If maya has to load your scene and it ends up loading nparticle systems that may not be cached etc that can cause trouble.
It sounds to me like the fluid isn't cached, and or I was wondering why in the heck you are simulating with Hermite instead of linear?
Hope the terminal command works for you, just be sure to run the Maya Terminal, and not just regular terminal (makes things alittle easier )
