NLB cluster [{param2}]: NLB detected a duplicate host priority {param5} that is shared between cluster hosts. Each host in the NLB cluster must have a unique host priority. Please check the NLB configuration of all hosts and make sure that each has a unique host priority (a number between 1 and 32).

Fields

Message

NLB cluster [{param2}]: NLB detected duplicate cluster subnets. This may be due to network partitioning; which prevents NLB heartbeats of one or more hosts from reaching the other cluster hosts.
