Hey Dulaj! As a contributor, I would go against the latest version, which is 0.9-SNAPSHOT.
It may be in your case that the JobManager actor is down, but the process still lingers. (BTW: I have a patch pending that makes sure the process disappears when the actor via down). Could you have a look at the log "flink-<user>-jobmanager-<host>-.log" and see if there are any errors logged?
