NetEngine NE40E-M2K---Lockup During Operation

Dear all,

We have 3 different clients that observe an episode of Lockup During Operation and we cannot have access neither through console interface.

The operation returned after power down the router.

Analising log file we can see at the same moment some ping commands realized by a user that is not a local user. Anyone already see this message? This is normal?
