Which ONTAP release are you running? But without seeing the core file it might become very much guess work.

[response · Accepted solution]

OnTAP release 8.1.3P3,
I found the similar case need to upgrade to 8.2.1 and later , but what is really root cause.

Does it happen during boot? Any other msg right before or after?

EMS shows any different message or additional info?

Without a core it is impossible to say. I would upgrade to 8.2.5P5 first and if it still happens engage Support.
