             Project: Accumulo
          Issue Type: Bug
    Affects Versions: 1.8.1
         Environment: * Ubuntu 14.04

I'm running into an issue across all environments where TabletServers are occupying a large number of ports in a CLOSED_WAIT state writing to a DataNode at port 50010.  I'm seeing numbers from around 12,000 to 20,000 ports.  In some instances, there were over 68k and it was affecting other applications from getting a free port and they would fail to start (which is how we found this in the first place).
