Dual SUP2T-10G - Standby SUP reboots when writing memory on active SUP

Hi everyone, 

I have an odd issue - 


Everytime I write memory on my 6509E with dual SUP2T-10G supervisors, the standby SUP reloads.

I upgraded IOS code on both bootdisk and slaveboot disk to the same version prior to doing more tests. 

I consoled into the standby SUP to see what happens when write memory is issue, and this is what is displayed:

Hi,

Hi,

It appeared to be a hardware issue as it behaves the same with different software versions.  I would open a ticket with TAC and ask them to replace the backup sup.

HTH
