2610XM with 12.2.13 - Unknown reason of system restart


We have started deployment of 2610XM with 12.2.13(is) on one of our customers network, and after few days running 12.2.13, I have noticed that most of these routers show an unknown reason of restart.

Typically, "show ver" output is :

#sho ver

System image file is "flash:c2600xm-is-mz.122-13.bin"

cisco 2610XM (MPC860P) processor (revision 0x100) with 61440K/4096K bytes of memory.

M860 processor: part number 5, mask 2

Bridging software.

1 Serial network interface(s)

32K bytes of non-volatile configuration memory.

16384K bytes of processor board System flash (Read/Write)

Configuration register is 0x2102

So, TAC engineering says we should not worry about this as there no indication of software or hardware failure.

I was wondering if somebody has already face similar issue, and if there is any explanation to such "unknown" reason of system restart.

You advice will be appreciated...

Thanks & Brgds,

Re: 2610XM with 12.2.13 - Unknown reason of system restart

Hi, HA,

This means that the system tried to save information about the crash into NVRAM but didn't succeed.

This is why the stack is empty and the crash is unknown.

Basically, when the box reloads, we set some variable in NVRAM according to why we reloaded. This

could be a bus error, software forced crash, a parity error, or hardware.

TAC needs to collect more info to anylize this. You may upgrade to the next code to see if the problem raise again.
