That's an awesome explanation @NullZero.... We are facing similar issues, but sort of different way... We have 2 node Search Head Cluster... among which one is static captain... another one is a member. Often the non-captain member goes out of cluster (It is not showing in the Search head clustering page).. every time we are manually restarting the Splunk or the entire EC2 of the member.. then it is showing in the cluster page.... Can i use the re-sync command to solve the issue, instead of restarting the Splunk or EC2? will it help? Thanks for your help 😊 ... View more
