What to do if the Unix Agent doesn’t react to the stop command anymore and can’t be stopped from the service-manager either.
You can stop it by killing the process that is running on the OS level. This way is brutal and doesn't allow the process to close itself, this will just kill it.
With this command you will get the list of running agent processes and you have to select the one which you want to kill
ps -ef | grep -i ucxjlx6
you can stop it with the command kill and as PID parent id of the process you wish to kill
kill -9 (PID)
