I have a new install running Splunk 6.4 on RHEL 7. I have a Search Head Cluster with 3 members and pushed the DB Connect 2 app out via the Search Head Deployer. I have Java 1.8.0_77 installed on all of my Search Heads and configured the correct path within the DB Connect app (/usr/java/jre1.8.0_77). The RPC server status icon shows green, however, I noticed upon page refresh it would switch to "Down" and then with another refresh goes back to "Up".
In the rpc.log I can see the RPC server consistently restarting, as seen here:
I have debug logging enabled but it doesn't show anything of value. SELinux is permissive, and normal system logs do not report anything related. Could this be a bug with 6.4?
I also tested on a non-clustered SH and got the same result.
