old gen filled up with objects - 100,000,000 instances each of WeakReference and LinkedBlockingQueue$Node,
owned by ConnectionQueryServicesImpl.connectionsQueue. The PhoenixConnection referred to by
the  WeakReference is null for all but the few active connections. I don't see anything in
the log - I can't confirm that it's logging properly though. Per the docs for ScheduledThreadPoolExecutor,
if the run method throws an error, further executions are suppressed.
