Logs: Get Called...Couldn't find xxxx

[lcatherine1234]

Hi

I have this kind of logs since I use docker version 20.10.17
Nov 28 16:31:55 server-adm docker-local-persist-plugin[2347]: Get Called... Couldn't find og586f8ghwvs
Nov 28 16:31:55 server-adm docker-local-persist-plugin[2347]: Get Called... Couldn't find og586f8ghwvs
....
Nov 28 16:31:55 server-adm docker-local-persist-plugin[2347]: Get Called... Couldn't find uow9os6b0x2o
Nov 28 16:31:55 server-adm docker-local-persist-plugin[2347]: Get Called... Couldn't find uow9os6b0x2o

The id that the logs return corresponds to the id of the docker service because I am using swarm.
The message appears in the logs every 30 seconds.
what does this message mean ?

thanks,
