CISCO 2951 Router Reboot

[XavierDArthur]

Hello,

Has anyone had an issue with a CISCO 2951 Router rebooting itself. When checking the show version for last reload, I am getting this following error: System returned to ROM by address error at PC 0x652B79C, address 0xDEADBEFB. Any insight on the cause of this error would be greatly appreciated.

address error at PC 0x652B79C

Looks for me some hardware issue, first I will try erase the Image and config (like factory reset) and configure again and test it.

if this is happening frequently, then replacing  device is advise (if this is in production network)

Is it always at the same memory allocation ? aka 0x652B79C, address 0xDEADBEFB ? 

how old is router? what is operation environment ?

Regards, ML

Martin,

Yes it is. the router is only a few months old but I am pretty sure it was refurbished. Its in a constant operational environment.

Post the complete output to the following command: 

1. sh version
2. dir

 - Probably a bug , upgrade to latest advisory release , if applicable : https://software.cisco.com/download/home/282774230/type/280805680/release/15.7.3M8 , check if that can help.

hi,

is your 2951 still covered under smarnet? end of support is dec 31, 2022.

try opening a TAC case and they'll usually ask for the crash file info, show tech, etc.

an IOS upgrade will usually resolve this kind of issue.
