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.

Greetings, First time caller.
I have a 520 for which "snap list" returns several snapshot_for_backup ( busy ) lines. These are old and for some reason were not deleted automatically. I cannot delete them manually either.
I have tried setting "snap sched vol0 0 0 0" turned "vol options vol0 nosnap on" and was still unable to delete the snapshots.
Below is the output of snap list.
Any suggestions on how to get rid of the unwanted snapshots would be appreciated.

Joe,
Please remember jsh is COMPLETELY UNSUPPORTED. If it crashes your filer, I'm not responsible and neither is Netapp :)
Having said that, you should try kill with other options. It's been a long time since I used this. Maybe you need to kill PID (i.e. 517).
