While debugging some memory issues with out application, we noticed that our RoutingService was reporting an ever-increating value for its periodic "physical memory" metric.
Figured we were configuring something wrong (with history, or lifespan, etc.)
But, if I run up a fairly plain RoutingService via the RTI Launcher (based off of the "DefaultDomainRoute" included in the "RTI_ROUTING_SERVICE.xml" shipped with RTI), I still see this metric increasing.
