[keycloak-user] The "Lost data because of abrupt leavers" message in the server logs

Hi, We are seeing the following FATAL logs message in server.log whenever a node leaves the HA cluster. 15:39:21,605 FATAL [org.infinispan.CLUSTER] (transport-thread--p14-t6) [Context=clientSessions] ISPN000313: Lost data because of abrupt leavers [ckey-ckey-1] I do not see any session lost when a node is leaving a cluster. Could you please confirm why this message is generate and is there actually any data lose at the time a node leaves the cluster? Can we prevent this FATAL message from showing in the logs? if so, how it is possible? -- Moe Doutaghy
