> When I set the spark.akka.frameSize to something over 10, the messages sent from the executors to the driver completely block the execution if the message is bigger than 10MiB and smaller than the frameSize (if it's above the frameSize, it's ok)
> Workaround is to set the spark.akka.frameSize to 10. In this case, since 0.8.1, the blockManager deal with  the data to be sent. It seems slower than akka direct message though.
> The configuration seems to be correctly read (see actorSystemConfig.txt), so I don't see where the 10MiB could come from
