Troubleshooting Common System Problems
Spurious Memory Accesses
A spurious memory access occurs when a CiscoIOS software process attempts to access memory in the
lowest 16 KB region of memory, which is a restricted location. Typically, such errors display a system
error message similar to the following:
%ALIGN-3-SPURIOUS: Spurious memory access made at 0x60968C44 reading 0x0
%ALIGN-3-TRACE: -Traceback= 60968C44 60269808 602389D8 00000000 00000000 00000000
00000000 00000000
Where possible, the Cisco IOS software handles spurious memory accesses by returning a value of zero
to the calling routine, and then displaying the above error message. If this is not possible, the router
crashes with a Segment Violation (SegV) error. In either case, the cause of the error is almost always a
bug in the Cisco IOS software.
If possible, upgrade to the latest release of the Cisco IO S software. If the bug still exists on the router,
see the section Spurious Accesses in the document Troubleshooting Spurious Accesses, Alignment
Errors, and Spurious Interrupts, at the following URL:
