**Other relevant data:**

systemctl status tomcat.service points me to /usr/share/tomcat/hs_err_pid1579.log

Which tells me:

A fatal error has been detected by the Java Runtime Environment

I searched this message and downgraded to:

Upgrading candlepin to 2.6.8 fixed my issue. It’s not in the Katello 3.9.1 repo unfortunately.

yum localinstall

Katello 3.9 is long out of support. The latest version in 3.14, with 3.15 coming out soon. I highly recommend updating your instance to a supported version.
