Brian,
Thanks for the reply.
I'm in the java shell and ps in fact returns several Ndmpd threads
even though > ndmpd status indicates no sessions active.

But when I try to kill, the following returns:

jsh> kill Thread-517
Arg expected

Is there a switch I'm missing, like kill -9 <threadName>

By the way the filer is running the most current version of ONTAP
for the model ( F520 )
and has been rebooted in the last 42 days which postdates
the timestamp on the snapshots.
It looks like the kill solution or boot from floppy into maintenance
mode and deleting them are going to be the only workable
solutions.

There is an unsupported java shell you can invoke and kill the ndmp
sessions. Even though ndmpd says no active sessions, it probably has
some snapshots locked.

filer> java netapp.cmds.jsh
jsh> ps
<grab thread names for ndmpd sessions>
jsh> kill threadName
jsh> exit
filer> snap delete vol0 snapshot-name
