Estamos tentando ler de uma fila do Amazon SQS a partir de um programa Java em execução em uma instância do EC2. Ocasionalmente, temos umcom.amazonaws.AbortedException. Nosso código fica assim:

AmazonSQSClient sqs = new AmazonSQSClient(myCredentials);
ReceiveMessageRequest request = new ReceiveMessageRequest()
            .withWaitTimeSeconds(20)
            .withMaxNumberOfMessages(1)
            .withQueueUrl(queueUrl);
ReceiveMessageResult result = sqs.receiveMessage(request);

E nosso rastreamento de pilha é assim:

A documentação paracom.amazonaws.services.sqs.AmazonSQSClient não nos diz para esperar uma AbortedException.

Estamos usando a versão 1.11.77 do SDK.

Qualquer ajuda seria apreciada. Obrigado.
