Default Broken Roller Rockers

What would cause full Roller Rockers to break at the trunnion? I have one that completely came apart and upon inspection, I discovered several others that are cracked/split at the trunnion right by the stud hole. Anyone ever experienced this? The Rockers are 1.65 PRW's.
