Microsoft System Center Configuration Manager (SCCM) is a Windows product that enables the management, deployment and security of devices and applications across an enterprise.
Use Case observed:
Release: CA Advanced Authentication release 9.1
Component: CA Advanced Authentication.
The " SCCM " back channel was configured to use port 8005 which is also Tomcat port where it listens for Shutdown requests. Any Apache Tomcat Server which was configured to use the same port which is by default 8005 wouldn’t work. Apache Tomcat Service couldn’t start.
Subsequently, all Apps including arcotafm, admin, arcotsm or anything in the Apache Tomcat deployed wouldn’t work.
Uninstall/Revert the Microsoft KB5022286 patch from the server and that should help restarting the Tomcat service as no port conflict is there.
If you are using the SCCM tool to deploy patches please make sure to disable the SCCM port 8005 after Patch installation and Restart the Tomcat service or change the Tomcat port in server.xml to listen on any other port than 8005.
