Environment
VMware NSX-T 3.x
VMware NSX 4.x
Cause
In some versions of NSX, there is an issue with a segment port being deleted before the Traceflow Config is deleted when trying to delete a Project in NSX Manager. This causes the validation to fail.
Resolution
FixedInVersion#4.2.0.0.0.23229422 and above.
The issue is resolved with changes implemented in NSX 4.2.0.0.0.23229422. If encountering issues with deletion of projects and receiving the noted error message, an upgrade to the fixed version or a higher one will be needed to be able to successfully delete projects from the NSX Manager.
If upgrading NSX Manager does not resolve the issue or if unable to remove Projects with a different error message, open a case with Broadcom NSX support.
