only part of the particles rendered

Hi,
I'm rendering a tyflow particle sim. It's a Birth voxels that hover in space and than start moving a certain way. I have a mesh in the tyflow stack. when i render i see only part of the particles but not all of them. in the viewport it all looks good. 
What should i do?
Thank you

Did you forget to put a Mesh operator in all of the events that you want to render?

No. A mesh is part of the event. I see the particles in the render but not all of them.

Well, I can't guess at the cause You'll need to post more info (screenshots, files, etc) for further help.
