Thank you Sir,
I have attached my struct file for you. For RMT I used 2.5 for Sb and 2.0 for S,  but when I set automatically RMT and cont.. editing the RMT of the two different atoms become same, i.e. 1.43. Also as you have said I lower the core-separation energy to -8.0 Ry and -10.0 Ry, and I got the same leakage (0.074 for Sb and 0.021 for S).

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,.....
