A router may experience a Spurious Memory Access when sending an SNMP trap on a Link Down 
event. Spurious access is an attempt by Cisco IOS Software to access memory in a restricted 
location.

This error has typically no impact on router behavior.

Spurious accesses are counted and recorded, if possible, by Cisco IOS Software. This information 
is available with the show alignment command. The traceback information is necessary to 
determine the cause and the fix of the spurious accesses.

This condition indicates a software failure. 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.

There are no known workarounds.
