Slf4j prints entire Map contents (#<I>)

Found this in <I>.x load testing.  



The Sf4j Logger will iterate collections calling toSting() on each entry in a map.  This causes severe degradation once the map reaches even a trivial size.  



Changed the debug statement to just echo the mapName and not pass instance to the LOGGER.debug().
