        TCP has a bunch of ports.  Servers can listen on ports, but only
one server can listen on a port at any one time.  This error usually
occurs if you try to listen on a port that is already in use.

        More technical explanation of the above:

        Now, to how the error message applies to your problem, that I
don't know.  Under Linux I'd use tools like netstat (with the -ldptun
options) and lsof to find out what was listening on that port, and ensure
that there was no conflict.  But I don't know how to do this on Solaris.
Have another go at it, and if you can't figure it out between you and
Google, maybe a Solaris person on the list could give you a hand if you
let us know what you've already tried (see
http://www.catb.org/~esr/faqs/smart-questions.html for how to ensure that
you've included all the information we want).

        Thanks,
