Port bounces and traffic will refuse to pass through the box even though there is link light and the other side will show up/up

This issue has been observed on multiple codes on the same box but not on another N9K-C93180LC-EX running the same code.

Adjacent or local port bounces and then the local N9K port will stay down/down while the other side shows up/up and there is even link light.
A couple of times both sides will be up/up but the traffic will refuse to pass through the N9K.
