The only phenomenon I know like this -

When rotor/stator clearances are tight (as in an engine fresh from the shop) the clearance may shink to zero after shutdown. This is because the lightweight case cools off faster than the massive rotor discs.

It may be impossible to crank the engine when this happens.

The situation resolves itself as the temperatures slowly equalize.
