there is a limit of 4 concurrent streams, the newer datamovers with 8G of memory can run more.

The ability to raise the number of concurrent NDMP backup streams from four to eight was introduced with the 6.0 family release. But, the Data Mover hardware must have 8 GB or more of memory to support more than four backup streams.
server_param server_2 -facility NDMP -modify concurrentDataStreams -value 8
