First guess:   Is your struct file correct ???

Sb is a fairly big atom and usually has large distances to its neighbors.
What is your RMT of Sb.

If you are forced to use a small RMT for "real" reasons, lower the 
core-separation energy to -8.0 Ry.   Still core leakage (must be 
terrible small spheres ???)

When using .lcore, your error information is completely unspecific. 
Nobody can help, but I doubt very much that it has to do with 
core-leakage, but the problem might be too large basis set due to 
unphysically small spheres,.....
