NDMP errors on VNX

We've running NDMP backups of several NAS shares off our VNX for several months, but lately we're getting failures. Nothing has changed on either end as far as I know. Here are entries from the activity log:

08/09/2016 13:21:50 ANR4399E NAS file server 10.1.80.55 is reporting NDMP
error number 2: Device 31914208 is in use. (SESSION:

Any thoughts? The drives appear to be working fine backing up normal TSM incrementals, but the NDMP backups started sporadically failing. Now they don't work at all.

It looks like a network issue with the NDMP protocol: http://www.ibm.com/support/knowledgecenter/SSGSG7_7.1.3/srv.msgs/ANR4399E.html

Restart the clients and/or check for network connectivity. Since you are using LAN Free, make sue that the LAN Free setup is working correctly.

By the way, if I were you, I would find a way to get out of the NDMP backup scenario. Too much headache and terrible performance regardless of what storage you are using.
