3845 router problem

Hi,

Our 3845 router is frequently getting reboot. After analysis we found the issue as below:

"System returned to ROM by bus error at PC 0x62474E44, address 0xB7B4F6AD at 18:11:36 KSA Mon Oct 24 2011".

We checked the router using command : "Show region" and found the following:

      Start         End     Size(b)  Class  Media  Name

0x0FFFFE00  0x0FFFFFFF         512  Iomem  R/W    BCM region

0x2D800000  0x2FFFFDFF    41942528  Iomem  R/W    iomem

0x60000000  0x6D7FFFFF   226492416  Local  R/W    main

0x6001A0E0  0x644080E3    71229444  IText  R/O    main:text

0x644137E0  0x6740BF9F    50300864  IData  R/W    main:data

0x6740BFA0  0x687E5A9F    20814592  IBss   R/W    main:bss

0x687E5AA0  0x6D7FFFFF    83993952  Local  R/W    main:heap

0x80000000  0x8D7FFFFF   226492416  Local  R/W    main:(main_k0)

0xA0000000  0xAD7FFFFF   226492416  Local  R/W    main:(main_k1)

After working on the output interpreter we found that could be an IOS issue.Let me tell u the IOS version:

" Cisco IOS Software, 3800 Software (C3845-ADVENTERPRISEK9-M), Version 12.4(24)T, RELEASE SOFTWARE (fc1)"

Kindly suggest and advice to resolve this issue.

Hi,

Have a look at this document on how to troubleshot bus crashes. You can also try loading a different release of IOS on your device.  If that does not solve the issue, then you need to open a ticket with TAC and send them the error messages. If it is a hardware issue, you need to RMA it to Cisco for replacement, assuming you have Smartnet contract for it.
