Comment 9 Lai 2020-11-18 15:48:36 UTC 
Steps to retest:

1. Set Pulp to use only 1 worker so that we can monitor the progress easily.  This can be done by modifying pulp_concurrancy=1 in /etc/default/pulp_workers
2. Restart pulp_workers: systemctl restart pulp_workers
3. Enable and sync rhel-7-server-rpms
4. Use the following command to monitor the memory usage.

watch 'ps -aux | grep reserved_resource_worker-0'

5. Create cv and add rhel-7-server-rpms
6. Publish cv
7. Monitor pulp worker from step 3

Expected:
Processing should not reach 3GB

Actual:
Processing took up to 1.3GB as highest memory consumption that I've seen.  It stabilizes around 1GB. 

Since we're below the threshold of 3GB, this is verified.

Verified on 6.8.1_snap 2

Checked pulp version on system as pulp-rpm-plugins-2.21.3.1-1.el7sat.noarch
