Description of problem:

While doing certain host build/rebuild/re-registration/deletion-related tasks, I have noticed the following errors in production.log at certain times.

2021-08-24T21:15:40 [E|kat|25e729cf] event_queue_error: type=delete_host_agent_queue, object_id=21

Version-Release number of selected component (if applicable):

Satellite 6.10 [ snap 13 ]

How reproducible:

Not always

Steps to Reproduce:
1. Install a satellite 6 and set it up for system deployment.
2. Deploy some RHEL 7 hosts concurrently from Satellite server and wait for their build to get completed.
3. Perform some re-registrations, host deletion etc
4. Execute --> grep \'Connection refused - connect(2) for "localhost"\' /var/log/foreman/production.log -B3 -A3

Actual results:

1. grep \'Connection refused - connect(2) for "localhost"\' /var/log/foreman/production.log B3 -A3

Expected results:

These should not occur at all.

Additional info:

I don\'t have any qpidd service running and based on the Engineering team, this scenario is occurring when satellite attempts to delete qpid queue when katello agent is disabled
