Hi Wajid,

Based on decoding the Cause reg - 0x00000414 & the Status reg - 0x500080e3 values it is understood that a write at a mis-aligned memory address has happened and this causes the device to reload. To understand if it is due to a software issue or a hardware related issue, I would require the below outputs for further analysis.

1) Show version

2) Show region

3) The traceback logs generated on the device

And if the device keeps continously re-booting without giving you a chance to even collect these requested information then replacement is the only option.

Kindly do the needful.

Taking out all modules for me solved the problem. Continuous reloads stopped, was a failed ATM-T1 module.


Anybody reading this start removing all modules first before router replacement / trash out.
