>
> If no acquirers are available to take permit of semaphore, the permit never gets release and any further acquirerers will wait forever. 
> On node shut down DataStructuresProcessor.dsMap gets cleared out prior to event listener being able to execute onNodeRemoved, hence owner is never cleared out if it was unable to pass to a different acquirer.
