Unable to find transaction 1 in any of my logical logs


(Srinathgudimetla) #1

I am setting up Neo4j cluster with 2 core nodes and few Read Replicas. For now, I have not added any Read Replicas. Using Neo4j Enterprise edition 3.5.0 and OS on all nodes is Ubuntu 18.x. No data has been loaded yet into the database.

Core 1 : 10.161.240.82
Core 2 : 10.161.218.172

I have configured the neo4j.conf file as described in this link: https://neo4j.com/docs/operations-manual/current/clustering/setup-new-cluster/#causal-clustering-new-multi-machine-cluster

Config file:

dbms.connectors.default_listen_address=0.0.0.0
dbms.connectors.default_advertised_address=10.161.240.82
dbms.mode=CORE

causal_clustering.minimum_core_cluster_size_at_formation=2
causal_clustering.minimum_core_cluster_size_at_runtime=2
causal_clustering.discovery_type=LIST
causal_clustering.initial_discovery_members=10.161.240.82:5000,10.161.218.172:5000
causal_clustering.discovery_listen_address=10.161.240.82:5000
causal_clustering.transaction_listen_address=10.161.240.82:6000
causal_clustering.raft_listen_address=10.161.240.82:7000

After starting the Neo4j service on both nodes, I see the below error for the 1st core:

What does this error mean and how to resolve it?
