NDMP restoration stalls

Hi experts,

I am on a restoring NDMP restoration job. I started manually restoring the data 3 days back and today I still find only few of the data is restored.

When I checked the activity monitor it shows "begin read" and the process stalled.

Checked for the bprm and bptm logs. Could not find any clues.

BTW I am having Netbackup 6.0 env with Storagetek nas box.

It would be grateful If I can some workaround for this issue. You may find the status of restoration in the screenshot.

Clik here to view.

Awaiting for valuble replies

Cheers
