It is not uncommon for a blockchain transaction to be stuck due to unforeseen circumstances. In such a case, the party who initiated the transaction can attempt to break it by double-spending the same coins in another transaction. This will usually result in one of the two transactions being rejected by the network, depending on which one is included in the longest valid chain.
