Have you guys seen this before? What is causing this:

Warning: Due to potential bad behaviour with rhnplugin and certificates, used slower repoquery calls instead of Yum API.

Chris,

I think it is because my ansible.cfg is set to: **stdout\_callback = unixy**

I was trying to get my ansible output to show a more human readable format instead of all this mess in the same line.

ansible 2.6.2  
config file = /etc/ansible/ansible.cfg  
configured module search path = [u’/root/.ansible/plugins/modules’, u’/usr/share/ansible/plugins/modules’]  
ansible python module location = /usr/lib/python2.7/site-packages/ansible  
executable location = /bin/ansible  
python version = 2.7.5 (default, May 31 2018, 09:41:32) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)]

This warning exists when the yum plugin “rhnplugin” is installed and enabled on your system. As the message states, there is a bad interaction between rhnplugin and certificates. As a result, we use a slower means to perform some tasks. We add a warning to explain this situation.

This was added as a result of the following issue: [https://github.com/ansible/ansible-modules-core/pull/1516](https://github.com/ansible/ansible-modules-core/pull/1516)
