Could not generate persistent MAC address for veth476ff90: No such file or directory

I'm seeing this error message in my Docker Swarm manager:

I would like to know the real impact of it as all the services are running properly but at some point I noticed some instability in my system, generating in some way an OOM that may lead to a PostgreSQL database inconsistency.

I also looked at the same issue over Stackoverflow and github but none of them is approaching me to a solution.

My OS is Oracle Linux 8.6
