      To reproduce, just fire up a mongod with SSL enabled and then to create/destroy connections:

      while (true) ; do echo "GET /" | openssl s_client -connect <host>:<port> ; done

      Non-Mapped virtual memory will gradually trend up. Attached screenshot from MMS shows the primary trending up while the secondaries stay flat.
