There are many potential reasons for a ball to crack. The hairline split is or seems to be the beginning of a serious crack. If it's been in climate controlled storage and it begins at the ring finger hole, I'd suspect that the cause if centered around that hole. Potential causes could be -
- pin too close to the hole.
- too much super glue used to glue the insert.
- hole not beveled properly.
- hole was drilled too fast with too dull a bit.

If it's less than a year old, I'd bring it back to where it was bought and see if they can help return it to LM. If it's more than a year old ...

Since the crack goes around the ball, it sounds like it's ready to go to that bowling ball graveyard.  The cover probably continued to cure over the time period, or possibly the core expanded.  As we use these balls the lane conditioner helps keep the covers more pliable.  If they sit too long, even at room temperatures, they can crack.  There are other possible factors, as charlest suggested.

Every ball that has ever cracked on me was sitting on a shelf in my office, but in all but one case, I hadn't thrown it for awhile.  One time I actually heard it crack, which was weird.

What did it sound like!?!?

It was almost a "pop" sound.  If you put two balls on the carpet and then roll one softly into the other that would be close.  Not a loud crack, jut a pop.  My descriptive skills are lacking on this one...

I know that sound. I last heard it when my Virtual Energy cracked and I was in the adjoining room. Even with all the balls I have in that room, somehow I knew which ball cracked.

Hard to describe the sound as it's very distinct and/or unique.
