STP Loop- Duplicate Correlation for STPTopologyChange

What does this message tell us "Duplicate Correlation for STPTopologyChange?" Is it safe assumption that we have STP issue if we see this message. Do we get this message on regular topology change or only when we have any issue like STP loop?

Hello,

I have not seen such a message yet. When exactly does this message appear? Where is it displayed or logged?

Best regards,

This message is from Network Node Manager (HP network monitoring system).

Looks like its an SNMP trap from Cisco works:

And a more recent version

Pass-Through STP Traps

SNMP Trap Corresponding DFM Event

STPnewRoot MajorAlarm

STPtopologyChange MinorAlarm

SNMP is not my strong suite, so I will let others chime in.
