Hi @clopmz, as you can read at https://docs.splunk.com/Documentation/Splunk/8.2.6/Installation/SystemRequirements Splunk Enterprise is supported for Linux kernel 5.4 and higher and RHEL9 has a kernel 5.14. I don't know why they divided Kernel 5.x and higher in two rows, but the first is for Splunk Enterprise and the second for Universal Forwarder. Anyway, Usually I found dome problem with old versions of Operative Systems, never with the latest version. Ciao. Giuseppe P.S.: Karma Points are appreciated 😉
