Apparently only appears if you do not run it as root. Should probably run it as the service user?

[totto]

The provisioning should handle such situations :)

Doesn't this happen because the app was started manually by someone not using the restart script on the ec2-user?

[totto]

It probably happens because it find wrong PID or PID/user combinantion

[StigLau]

correct. Initctl can't control UserIdentityBackend if it didn't start it and has the PID

[totto]

pids=$(pgrep )
will get you the pids of all processes with the given name. To kill them all, use

kill -9 $pids
To refrain from using a variable and directly kill all processes with a given name issue

pkill -9
