At an educated guess, no? Are you running Forestry 2.0, and/or were you using a fortune pick? Even with either/or of these, I'm thinking you just ran over a bug.
There is another thread that was discussing this yesterday. People have gotten between ~1/2 stack to 5 stacks of apatite ores in a vein (not the apatite itself). It was also changed to drop between 1-5 apatite a break (more with fortune).
