What is taking up so much space in /var/lib/pulp?

Greetings, hope someone can share some insight here. Running Red Hat Satellite 6.2.9.
The installation doc states that with RHEL 5,6 and 7 synchronized, the runtime size is 500GB. I understand that is an estimate. I only have RHEL 6.3-6.9 and 7.1-7.3 synchronized, I only have optional/debug repos enabled for 7.2 and 7.3, some HA/RS repos and capsule server. Yet /var/lib/pulp is pushing 600GB and I can't expand it right now, my hardware is maxed out. I have disabled the repos I don't need and I've manually ran the cron job to clear orphaned content, yet I was only able to free up about 1GB. Is there any other tool I can run to find unnecessary content, or a certain configuration to avoid that could be wasting space? Just looking for some guidance, thank you.
