Fabric Child Container can't be started - java.lang.IllegalStateException: Instance already started

Issue

• VM running a parent/child containers went down.
• After VM came back, one of the child containers is in dodgy state.
• It is not running, there is no PID and Fabric shows it as "starting" and not connected.
