Atualização: o problema é relatado na versão 1.9.1 e não está presente em versões atualizadas do Docker.
Eu tenho um aplicativo docker em execução no elasticbeanstalk que trava após cerca de 10-11 dias de tempo de atividade.
O aplicativo executa um trabalho cron a cada minuto. Não há processo de aplicação de longa duração (meu).
Depois de travar, ele não responde mais às solicitações HTTP.
Seguinte docker comandos travar: top, exec, restart
docker logs responde, mas não mostra nenhum erro.
Eu não sei como depurar mais a partir deste ponto. Alguma ideia?
docker inspect mostra:
