For last few days I am getting the following log to my Cisco 1841 Router.
%ALIGN-3-SPURIOUS: Spurious memory access made at 0x61656290 reading 0x4
%ALIGN-3-TRACE: -Traceback= 0x61656290 0x61655528 0x614FA270 0x614FA254 0x0 0x0 0x0 0x0
%ALIGN-3-TRACE: -Traceback= 0x616562D4 0x61655528 0x614FA270 0x614FA254 0x0 0x0 0x0 0x0
As per Cisco:
%ALIGN-3-SPURIOUS: Spurious memory access made at [hex] reading [hex]
A spurious access occurs when a process attempts to read from the lowest region of memory. This portion of memory is reserved and should never be accessed. An attempted read operation to this region of memory is usually caused by the return of a nonexisting value to a function in the software.
Recommended Action: The system has detected the illegal access and was able to correct it without a system failure. This condition indicates a software failure. To take advantage of recent fixes, upgrade your system to the latest Cisco IOS software release in your release train. If this message recurs, enter the show log, show alignment and show tech-support commands, contact your Cisco technical support representative, and provide the representative with the gathered information.
%ALIGN-3-TRACE: -Traceback= [hex] [hex] [hex] [hex] [hex] [hex] [hex] [hex]
This tracing message provides information about a previous ALIGN error.
Recommended Action: Copy the error message exactly as it appears on the console or in the system log, contact your Cisco technical support representative, and provide the representative with the gathered information.
The same has been informed to Cisco and also the router has fully replaced. But after replacing the same is reflecting to router log.
IOS : System image file is "flash:c1841-advsecurityk9-mz.124-3d.bin" and c1841-advsecurityk9-mz.124-1a.bin (with the both we are getting the same log)
