It's an error message from your server, so it's not something Gnus
output.

I'm not too familiar with IMAP, is there some verbosity setting I can set,
to trace which IMAP command the server is responding to with the "No such
file" error, so that I may trace what's wrong in my server setup? I'd like
to use No Gnus, however would like to keep my old mail etc. and not have
to set up everything from scratch on the mail server side...

Your conversation with the server ends with:

* BYE [ALERT] Fatal error: No such file or directory

I have no idea where to begin debugging that.  Anybody?

You can run some IMAP servers from the command line (at least Courier)
and they'll authenticate as you.  So then you can just feed them IMAP
commands (and you can find the sequence of commands that trigger the
error from your log).  I don't know if that will work for you but hope so.

What Emacs version are you using?

GNU Emacs 24.0.50.1~bzr99756

It's the same with the latest bzr pull though.

I set up a clean testing IMAP mailbox on hcoop.net to see if it could be
some existing IMAP mailbox misconfig.

Now the Inbox is empty and there's no other folders, I have not sent a
single message to/from this account.

I get the same errors with this setup.

How can I debug this to see what's generating the fail to see what's wrong
with hcoop's setup? hcoop admin told me the traces don't reveal anything
descriptive to him, i.e. no idea which command is generating the Fatal
error

Thinking about this a bit more, I think the message may be coming from
setting errno to -1 somewhere, because that's the "No such file or
directory" error, I think.

And gnutls.c returns -1 here and there, but should probably set errno to
something...

Anyway, the means that the problem is that the IMAP server is saying
"* BYE" and closing the connection.  Why would it be doing that?

I've opened a bug about this on hcoop and the admin seems to thinks it's a
problem with Gnus after the recent changes.

Is there any way that Gnus would be forcing a hangup?

I.e. is there a way I can get a full trace of the sessing with Gnu Emacs
Gnus, since it doesn't have this problem? I.e. why is the server not
closing the connection there, as it's the same Gnus init setup etc.?

Gnus never hangs up the connection unless you request a shutdown/sleep.

The *imap log* buffer has all the commands Gnus sends to the IMAP server.
