Gnus regularly auto-saves what articles you've read etc, and when you
hit `s' in *Group* or quit Gnus it saves that information to
~/.newsrc.eld and deletes the auto-saved file.  So when it asks you that
question on startup, it means that you've not properly quit your
previous Gnus session.  Maybe you simply killed emacs without quitting
Gnus before?  Or maybe there's another Emacs session running Gnus

That's how it's supposed to work.  Does the echo area indicate what
server it checks when it hangs?

What you can also do is `M-x toggle-debug-on-quit RET' before you update
with `g'.  Then, when Gnus hangs for a while hit `C-g'.  That will show
you a backtrace which you can post here.
