Do you run gnuserv ?  Only one instance of gnuserv can run per user,
so if you start it a second time in a second copy of emacs it'll die
straight away - perhaps just before you try starting gnuserv in your
.emacs you could run "gnuclient -eval '(gnus-alive-p)'" and see what
it says - if there's already a copy of XEmacs running gnuserv that's
running gnus, it'd work.

Of course, if you're in the habit of running multiple copies of
XEmacs, you'd prolly want to make sure that only the one running Gnus
is the one that runs gnuserv...

HTH.
