Hello, Can someone try to explain what this Catalina.log snippet is saying in regards to clustering status?
It looks like to me, this machine successfully sent a session data state msg to the other machine in the cluster, but 60 sec later the other machine did not respond with with its session data state ********************* INFO: Starting clustering manager at [##0001] Apr 18, 2024 9:42:21 AM org.apache.catalina.ha.session.DeltaManager getAllClusterSessions INFO: Manager [##0001], requesting session state from [org.apache.catalina.tribes.membership.MemberImpl[tcp://{127, 0, 0, 1}:4001,{127, 0, 0, 1},4001, alive=2087779, securePort=-1, UDP Port=-1, id={-96 81 2 46 1 32 64 76 -97 -53 -48 3 -22 122 -8 28 }, payload={}, command={}, domain={}]].
