What:
An uncontested Travel infraction is called and the thrower has not released the disc.

Result:
Play does not stop. The thrower must establish the pivot at the correct spot as per rule 18.2.6.

Extra:
If uncontested, all players, except the thrower, are free to move anywhere on the field. If contested, play stops and players should return to where they were when the travel was called. If the thrower fails to establish the pivot at the correct spot before throwing the disc, this is violation as per rule 18.2.7. If the pass is incomplete, play continues. If the pass is completed, play stops and the disc is returned to the thrower.
