only one backburner server rendering out black frames, rest render fine

[chow choppe]

hi all

 

i am using 4 machies as server and rendering frames of animation using backburner.

now everything loads succesfully on all machines and all servers start rendering without any error. now the problem is that one of the servers is rendering out complete black frames whereas the remaining three are rendering frames perfectly.

 

i have tried to find the solution online but not been able to.what went wrong with this server as its log also doesnt show any errors.

Please help

 

thanks
