I have issue in one of my VMware Cluster servers, Event id 1135 occurs and restart the cluster service automatically all the cluster resources are went offline. Kindly find the Event it information below.
System Event id 1281
Joiner tried to Create Security Context using Package='Kerberos' with Context Requirement ='67586' and Timeout ='30000' for the target = 'node-a' 4 times.
After that Event id 1135
Occurred and Cluster node 'node- b' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster.
Event id 1251
Cluster network interface 'node a - Public' for cluster node 'vwsql01a' on network 'Cluster Network 1' is operational (up). The node can communicate with all other available failover cluster nodes on the network
Event id 1049
Cluster IP address resource 'SQL IP Address 1 (Cluster group)' cannot be brought online because a duplicate IP address 'xx.xx.xx.xx' was detected on the network. Please ensure all IP addresses are unique.
