You have checked that there isn't one already running (eg by telnet 
localhost 7300)?

otherwise:

sudo netstat -tap

look for things already started on port 7300, my /etc/services does not 
have anything defined for 7300 so it should be obvious.

As per the installation manual. Stick a line like:

sp:2345:respawn:su -c "perl /spider/perl/cluster.pl > /dev/null 2>&1" sysop

(all one line) in /etc/inittab, then either reboot or sudo telinit q
