Hi all!!

I am getting a warning while running OpenMC-0.10.0 but i am getting results.

WARNING: Maximum number of sites in fission bank reached. This can result in  
irreproducible results using different numbers of processes/threads.

What is the meaning of this warning??Is this warning has any significance or not??
