Cisco Nexus: "STP topology change in progress which can impact ISSU. As a precaution ISSU is rejected."

This message actually caused a Nexus 7K to fail on an upgrade.
Error: "STP topology change in progress which can impact ISSU. As a precaution ISSU is rejected."

All I did was wait a few minutes and ran it again.  It was successful the second time.  Just thought this was interesting.
