After Effects Rendering on Pc Renders

Hello All,  

 I'm a  Render TD , and I've been running into this problem  with After Effects.  So  here's the prboem.  I have a group  of  machines that render  After Effects, and  what's   happening is that  on these machines the rendernodes are producing   0kb frames.  On  almost  all renders.  I have  done stuff like enable  local rendering to see if that'll help it out. I have re started machines and cleaned them up .   I'm not  sure what's  happening   here.     If anyone  could help  out  that would be great. 

Regards,
