**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:
java-1.8.0-openjdk-1.8.0.222.b10-1.el7_7.x86_64
java-1.8.0-openjdk-headless-1.8.0.222.b10-1.el7_7.x86_64

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

yum localinstall http://koji.katello.org/kojifiles/packages/candlepin/2.6.8/1.el7/noarch/candlepin-2.6.8-1.el7.noarch.rpm http://koji.katello.org/kojifiles/packages/candlepin/2.6.8/1.el7/noarch/candlepin-selinux-2.6.8-1.el7.noarch.rpm

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.
