Milt,
This is not uncommon and is certainly not a rejection !
As Barit says usually happens on engines fresh from the shop especially when the 3 minute idle cool down is reduced.
Usually what happens is a very short run down then engine found the be locked up.
Manual recomends allow to cool and restart when engine is free obviously checking things like filter and MCD's.
Usually the areas causing the lock are self clearing ( Like tip seals ) and normally the engine will continue a long and happy life
Have had it on 219 engines on initial runs and then no problems after that.
