Basically everything in the rocket launch is automated, there was a primary and secondary mission on board the rocket. When a problem happened with one of the engines it was shut down and still was able to complete the primary mission which was the dragon capsule but it had to consume extra fuel in order to do so and that left the secondary mission without enough fuel to deliver the orbcomm satellite within the required safety margins of the ISS. So in that aspect the rocket did exactly what it was supposed to do, it saw a problem and dealt with it completing its primary mission at a sacrifice of its secondary mission.

Edit: It could also be the case that it did have the required fuel but part of the agreement with NASA was that if any anomaly should happen that the secondary mission is aborted or that it had a specific time window where it was allowed to start its engines back up to deliver the second payload and it missed that window because it took longer to get to orbit.
