Dear Quintin.Mayo,
How did you come to the conclusion that your Publisher is affected by the defect you are posting?
That defect you mention refers to a misleading output when running command utils diagnose test. Also, after running command show perf query class "Cisco Tomcat Web Application" you need to look at the perfmonservice2 requests. Your comment was made about the _root Errors, Requests and SessionsActive.
In any case you don't need to worry about them. It is expected to see them, I ran that same command in my lab and have higher numbers than what you are sharing.
Hope this information helps,
Sincerely,
Marco R.
