I hava a gluster replica 3 volume, there are about 10 clients, and clients has little file to read or write, but the server cpu consumption is very hight, about 500%~900% until I turn cluster.entry-self-heal, cluster.metadata-self-heal, cluster.data-self-heal, cluster.self-heal-daemon off.
following is the log of a brick of the replica volume.
