We received a notification from AWS at 6:27 PM EST on 1/7/15 about an unhealthy search node. search-prod1 became nonresponsive; attempts to connect to it via SSH, etc. failed.
I have tried to reboot the instance from the EC2 console panel, with no obvious success.
I have tried to stop the instance; it got stuck in the stopping state.
I tried to stop it again, which should have run a "force stop" state, but it remains stuck in the "stopping" state.
