Foreman v2.3.3 with Katello v3.18 - I ran into the “too many open files” problem when syncing OL7 so did a fresh install of newer version.
Foreman v2.4.0 with Katello v4.0 - OL7 now syncs perfectly but the main RHEL7 repo https://cdn.redhat.com/content/dist/rhel/server/7/7Server/x86_64/os fails/dies and the workarounds aren’t helping.
I have a snapshot of the VM before the Foreman installation so I’m going to see if I can get v2.5.0 with Katello v4.1 going…
