Re: [androidbrasil-dev] ETIMEDOUT em Socket

16:19 |

Olá Geovani,

Tem um cenário em que isso acontece, não sei se é o seu caso.

Se o RabbitMQ estiver rodando em cluster (exemplo: ambientes de HA [alta disponibilidade] da Amazon), o timeout pode coincidir com o momento em que a máquina ativa é trocada. Essa troca pode acontecer quando o balanceador detectar que não houve tráfego de dados em um socket por um determinado período (por exemplo, se a conexão do dispositivo com a fila não estiver recebendo heartbeats periodicamente). A sugestão então seria setar um intervalo de heartbeat (isso é feito na string de conexão) ou então tentar reduzir o intervalo já definido.

Espero que ajude.

Att,
Rodrigo

Bom dia Galera,

Estou tendo problemas com Sockets, no Android 4.4 até o 5.1.1; Preciso manter uma conexão ativa; Estou adquirindo um WakeLock e um WifiLock; Usei Socket.setSoTimeout(0) e ConnectionFactory.setConnectionTimeout(0), porém estou recebendo constantemente a seguinte stack trace:
