This was observed with nvme-cli-1.16-5.el8 and can be seen in the following job:

https://beaker.engineering.redhat.com/jobs/6996650

Below are the contents of my discovery.conf:

-t tcp -a 172.16.0.101 -s 4420
-t tcp -a 172.16.1.101 -s 4420
-t tcp -a 172.16.0.102 -s 4420
-t tcp -a 172.16.1.102 -s 4420

FYI, the connection to the namespaces are not impacted.
