Issue description
When requesting a node restart via JMX, for example from the admin console, the node console output shows that many reconnection attemps occur before the actual restart: 
node process id: 32, uuid: 266A905F-B6BE-D000-8A42-9D92ED558D95
... a total of 110 of these identical lines! ...
