Ich habe seit einiger Zeit mit aws Java API mit nicht so vielen Problemen gearbeitet. Derzeit benutze ich die Version 1.5.2 der Bibliothek.

Wenn ich die Objekte in einem Ordner mit dem folgenden Code durchlaufe:

AmazonS3 s3 = new AmazonS3Client(new PropertiesCredentials(MyClass.class.getResourceAsStream("AwsCredentials.properties")));

String s3Key = "folder1/folder2";


String bucketName = Constantes.S3_BUCKET;
String key = s3Key +"/input_chopped/";

ObjectListing  current = s3.listObjects(new ListObjectsRequest()
        .withBucketName(bucketName)
        .withPrefix(key));

boolean siguiente  = true;

while (siguiente) {    

    siguiente &= current.isTruncated();
    contador += current.getObjectSummaries().size();

    for (S3ObjectSummary objectSummary : current.getObjectSummaries()) {        
        S3Object object = s3.getObject(new GetObjectRequest(bucketName, objectSummary.getKey()));
        System.out.println(object.getKey());
    }

    current=s3.listNextBatchOfObjects(current);

}

Caught an AmazonClientException, which means the client encountered a serious internal problem while trying to communicate with S3, such as not being able to access the network.
Error Message: Unable to execute HTTP request: Timeout waiting for connection from pool

Irgendeine Idee, wie man diesen Fehler vermeidet. Es kommt nur in Ordnern mit einer Anzahl von Objekten vor, in diesem Fall befanden sich 463 Dateien darin. Vielen Dank
