Ouch! None the less, it does show an amazing bit of careful scrutiny for them to catch things before a big negative event.
I was surprised reading that the engines are checked after firing but before launch, presumably to abort before liftoff.
Didn’t realize they had that capability. Once again, leaving as little as possible to chance.

SpaceX has released a statement on today’s postponement:
“Today’s Orbcomm launch attempt has been scrubbed to address a potential concern identified during pre-flight checks. The vehicle and payload are in good condition, and engineering teams will take the extra time to ensure the highest possible level of mission assurance prior to flight. The rocket will remain vertical on the launch pad with the next available launch opportunity targeting Tuesday, June 24th.”
