another observation.. see second start "0.899 seconds" not possible.. seems second 1 not real start logstash connection gone..

what may reason second start? should check , investigate;

from documentation:

applications use spring-boot-devtools automatically restart whenever files on classpath change.

you can exclude resources or disable restarts.
