Im not an expert, but it seems to be an already binded port. Ok, less
technically: every service/daemon/program using TCP/IP (or UDP) on a
machine needs a connection point called "port", where clients can
connect to. smbd uses port 139 and nmbd uses port 137 (see
/etc/services for protocols and there correspondent ports, smbd uses
netbios-ssn, nmbd uses netbios-ns). Another famous examples is the
http-protocol used by web-servers and -browsers on port 80.

So in our case some service/program has port 139 already in use and
137 was still free. The question is now how to find out which daemon
blocks 139. I would suggest a glance to /etc/inetd.conf. Search for
netbios, maybe another daemon has an entry using the port. Second, you
can use "lsof" as root and search for TYPE inet. There you can find
the daemon locking port 139, I hope.
