Loop infinito com condição de saída inalcançável

A aplicação entra em um loop (iteração) cuja condição de parada nunca é verdadeira ou nunca é checada, trancando a execução indefinidamente. Isso causa travamento, consumo excessivo de CPU, negação de serviço ou congelamento de funcionalidades críticas.

Ejemplo

Um servidor web com while(true) lendo dados de rede, mas a condição de encerramento da conexão nunca é avaliada corretamente; ou um aplicativo mobile em loop aguardando uma resposta de API que nunca chega, sem timeout definido.

Cómo mitigar

Sempre defina condições de saída claras e alcançáveis (break, return, exceção); implemente timeouts em operações de I/O e loops que dependem de eventos externos; use ferramentas de análise estática para detectar loops sem saída óbvia; considere usar watchdogs ou sinais de interrupção como fallback.
