Description
Restarted the docker daemon, seeing the following warning message in the dockerd log:
Sep 26 09:43:52 redacted.redacted dockerd[39178]: time="2025-09-26T09:43:52.446171446-07:00" level=warning msg="Error (Unable to complete atomic operation, key modified) deleting object [endpoint_count 009a8baba4bdd54c8cedd64e7b2a61ea85572671cb8d8a21e675f389ae64c70e], retrying...."
This message is confusing to our users, as it appears the docker daemon failed, although that is not the case, as docker commands continue to operate as expected.
Reproduce
systemctl start docker
docker network ls (note the ID of the bridge network)
systemctl restart docker
journalctl -b -u docker|tail -n20 (note that the Error deleting object message contains the bridge network ID saved above.)
Expected behavior
No warning message about error deleting object for the default bridge network,
