It's a fresh Splunk tar, but the cluster is in use with deployed apps/configuration, so I don't want to delete everything and start over. The only thing I did to the SH was set the licenser, cluster-config, shcluster-config, and the deployer. This is the only line in the log to indicate the problem.
Anyone else seen this issue or any suggestions on how to fix? I've restarted the whole cluster with no change.
