Re: %ALIGN-3-TRACE: -Traceback=

This is an alignment error followed by a correction. How often are you seeing this error? Is it disrupting service? Can you post a 'sh log' ?

     As per my understanding... This is a log output for a spurious access. Plz check the document. It is related to software.
