%ALIGN-3-SPURIOUS: Spurious memory access made at 0x60988D34 reading 0x0
---------------------------------------------------------------------------

Description

On Cisco devices, a Spurious Memory Access occurs when an IOS process attempts to read from the lowest 16KB region of memory. This is always a software bug because access to this region is restricted.

There are two ways to detect spurious memory accesses:

Execute the router# show align hidden EXEC command
Check the router logs using the router# show log EXEC command

Spurious memory accesses are also reported in crashinfo files, usually displayed just before the stack dump.

Spurious memory accesses are not fatal on on MIPS-based platforms because IOS returns a null value to the calling routine and displays the errors above. However, spurious memory accesses will cause a PowerPC-based platform to crash with a SegV (Segment Violation) exception.

Report issue to Cisco and get the necessary bug fix.
