AWS Java SDK 1.9.3

Al descargar muchos archivos grandes (~ 3Gb) de AWS S3 en la aplicación de servidor Java, de vez en cuando obtengo SocketTimeoutException de la siguiente manera:

Descargo archivos de S3 usando 4 hilos, todos los hilos usan la misma instancia de TransferManager. Como se mencionó anteriormente, estoy usando AWS SDK 1.9.3 y obtengo tales excepciones solo de vez en cuando. El código es el siguiente:

...
Download d = transferManager.download(currentBucket, remoteFileName, new File(tmpName));
d.waitForCompletion();
...

¿Es un problema de SDK? Tal vez de v1.9.3?

¿Y hay alguna solución, excepto aumentarsocketTimeout paraClientConfiguration?
