haarcascade finger-tip detection and image prep

I am trying to create a haarcascade to detect finger tips. I have recorded two hands in HD videos each 20 seconds in length. Then extracted the BMP images in a set of positive images. The images are from the top of the hand with the finger nails showing and the bounding boxes created around each finger tip with the nail - 4 per hand. After running a bounding box .cpp app to use createsamples then ran a training session for 10 hours where it completed 4 stages out of designated 10 and terminated.

I am baffled as to why it terminated when I have a set of over 1500 pos images and nearly 2000 negative images of random pictures.

Testing detection of the finger tip was a failure - no detection of the objects bounded.

Advice? Thank you!
