Sorry for the tardy response (busy at work. :)).   Here’s the command and output (run from the SmartOS box):

ssh -c arcfour256 root at freebsdnas zfs send -R tank at daily20140920 | zfs receive -v -F zones/tank 

The output (after running for a long time xferring data):

receiving full stream of tank at daily20140920 into zones/tank at daily20140920
received 1.35GB stream in 15 seconds (91.9MB/sec)
receiving full stream of tank/photography at daily20140920 into zones/tank/photography at daily20140920
Read from remote host nas00: Connection reset by peer
cannot receive new filesystem stream: invalid backup stream


Is it possible the command is simply timing out for some reason and closing the connection?
