When I use java S3ObjectInputStream create 30 threads simultaneously download, there have been some problems.

The following is the use of java S3ObjectInputStream：

byte[] buffer = new byte¹⁰²⁴⁰;
S3ObjectInputStream ins = conn.getObject(bucketName, objectName).getObjectContent();
while ((readSize = ins.read(buffer, 0, 10240)) != -1) {
//dosomething
}

radosgw log error：
