Hi Asif,

the wrapper script tries to do what systemd already does. Trash it and
write your own .service. Especially the »su« in such scripts breaks
things, because it creates its own login session via PAM.

Check all the wrapper scripts called and how they interact, so you
actually get to the plain java call.

The file you attached actually has systemd support. Try
»/opt/atlassian/remote-agent/bin/bamboo-agent.sh install«
