Liberação ou encerramento inadequado de recursos

Quando o software não libera corretamente recursos (conexões de banco, arquivo aberto, memória alocada, socket de rede) após o uso. O programa continua consumindo esses recursos até ficar sem espaço ou conexões disponíveis, causando falhas, lentidão ou negação de serviço.

Ejemplo

Um servidor web abre uma conexão com banco de dados para cada requisição, mas esquece de fechar a conexão quando termina. Após centenas de requisições, todas as conexões disponíveis estão esgotadas e novas requisições falham.

Cómo mitigar

Use padrões como try-with-resources (Java), context managers (Python), ou equivalentes na sua linguagem para garantir liberação automática. Implemente timeouts e monitore uso de recursos em produção para detectar vazamentos cedo.
