Re: 3845 failure..

Hi Tam,

From the Show version o/p,

This router was last restarted by a bus error:

'bus error at PC 0x605A80F4, address 0x702B82E8 at 10:19:56 UTC Wed Oct 11 2006'

The system encounters a bus error when the processor tries to access a memory location

that either does not exist (a software error) or does not respond properly (a hardware

problem).

TRY THIS: Issue a 'show region' and check if the address location (the 'address'

part of the bus error) falls within an existing address range. If the address reported

by the bus error does not fall within the ranges displayed in the 'show region'

output, this means that the router was trying to access an invalid address. This

indicates that it is a Cisco IOS Software problem. Paste the output from the 'show

stacks' command to decode the output and identify the Cisco IOS Software bug that

is causing the bus error. If the address falls within one of the ranges in the

'show region' output, it means that the router was accessing a valid memory address,

but the hardware corresponding to that address is not responding properly. This

indicates a hardware problem. Try reseating the hardware belonging to this address

range before attempting to replace it.

Rate if it does,

Rgs

thanks for the reply, and yes it was rebooted due to a bus error but that was one week ago and it came back to normal with no problems until today show the following errors:

I was able to resolve this

I was able to resolve this issue by  replacing DRAM sticks.
