The distance between some ions is very small

Using the POSCAR below, I did many static calculations, but when I try relaxing ions, vasp goes angry and says: "WARNING! The distance between some ions is very small | please check the nearest neigbor list in the OUTCAR file | I HOPE YOU KNOW WHAT YOU ARE DOING"! Actually Vasp complains after many ionic steps.
