Jenkins continuously trying to stop already stooped slave.

Feb 28, 2018 5:07:51 PM INFO hudson.plugins.ec2.EC2RetentionStrategy internalCheck
Idle timeout of Ubuntu-2018.02 (i-00c5cf33cb559c286) after 174 idle minutes

I have timeout for 10 min, and after that instance was shutdown successfully

instance exist in the list as "offline", but not stopped (or it is expected behavior?).

I can manually start instance just pressing "launch agent" button, but instance is not starting back on demand.
