Hello,

Upon boot, my apache tomcat Jenkins instance throws the below error. I understand that my Tomcat is starting as non-root hence can bind to port 22, but what is it trying to do here? The os is already running a SSHD process, why is Jenkins trying to start another instance? The server does seem to continue to start and function ok, but why the error? What is broke as a result of not binding?

Thanks for any and all help

Ken
