0.16.0 initialization errors, badly constructed host:port names for the dynamically bound ports?

We occasionally see the following error messages in our logs.

The base parameter has not been changed in hadoop-default.xml or 
overridden in hadoop-site.xml

<property>
  <name>mapred.task.tracker.report.address</name>
  <value>127.0.0.1:0</value>
  <description>The interface and port that task tracker server listens on.
  Since it is only connected to by the tasks, it uses the local interface.
  EXPERT ONLY. Should only be changed if your host does not have the 
loopback
  interface.</description>
</property>
