In a kitchen run, "chef-client" cookbook v12.3.3 failing on Redhat 6.10 while v12.3.2 works OK

[tas50]

In a 'kitchen test' run, a policy using "chef-client" cookbook v12.3.3 or 12.3.4 is failing on Redhat 6.10 while v12.3.2 works OK. All of our cookbooks run to completion with no errors yet with v12.3.3 kitchen throws the following error:

Converge failed on instance .

To Reproduce

Using chef-infra-client version 16.2.73
Running on a Redhat 6.10 VM

We have a policy with recipes/default.rb containing:
include_recipe 'chef-client::config'
include_recipe 'chef-client'
and a Policyfile.rb file containing:
cookbook 'chef-client', '= 12.3.2'
and things work.

Changing the pinning to 12.3.3 it fails. 12.3.4 (the most recent) also fails

Expected behavior

I expect the kitchen run to finish successfully.

Actual behavior

The .kitchen log file shows:
