> When running a secure data node, the default ports it uses are 1004 and 1006.
> Sometimes other OS services can start on these ports causing the DN to fail
> to start (eg the nfs service can use random ports under 1024).
> When this happens an error is logged by jsvc, but it is confusing as it does
> not tell you which port it is having issues binding to, for example, when
> port 1004 is used by another process:
> {code}

> We should catch the BindException exception and log out the problem
> address:port and then re-throw the exception to make the problem more clear.
> I will upload a patch for this.
