After Effects 0KB Render Problems

Hello All,  

First  time posting here.  I was wondering, if any one here  has ran into  After Effects  renders  rendering  0kb  frames.   Every time I render  After Effects files,  I'm running into  0kb  frames.  I do  not  know how to solve this.  Also this  happens   speratoically.    It's very  difficult  to track down the causes. Is there a general  fix for  0kb frames .  We  render After effects  on Pc-Render nodes.  

Regards,
