Hi,
I'm using inbox.comp.version-control.git for a few days now, and it
worked fine till now. I'm using Gnus from within Emacs to access it via
NNTP.
Just a few minutes ago, however, attempts to enter the
inbox.comp.version-control.git from Gnus started to give "Server closed
connection" error, even though some other groups on public-inbox still
work fine.
The only difference I see is that inbox.comp.version-control.git has
much more messages than most of the other groups on the
public-inbox... wait...
Here are 3 fattest groups, and none of them I can visit from Gnus:
438320: inbox.comp.lang.ruby.core
438320: inbox.comp.lang.ruby.dev
341199: inbox.comp.version-control.git
To check if it's Gnus problem, I've just visited:
1523921: gmane.linux.debian.devel.bugs.general
and it works fine.
Any idea what's wrong between Gnus and public-inbox for large groups?

Uh oh, did you notice any delay in how long it took for you
to see this message from when Gnus started connecting?
I'm not familiar with Gnus or Emacs at all, but is there a way
you can show me a protocol dump?

Eeek, I noticed 438320 was introduced via ruby-talk; so maybe I
have a bug in that causing messages to leak into the other Ruby
lists I follow :x

OK, 341199 looks reasonable.

Not sure, I haven't made any changes to the code running on
"public-inbox.org" in a few weeks, now. I suspect there's a
fairness problem in the NNTP server in how it handles XOVER
and that might cause timeouts in clients.
Fwiw, I might not be online much the next few days.

I just deployed this RFC on news.public-inbox.org and hope it
improves things:

Lets hope we get to the bottom of this quickly :>

It's about 4 seconds after Gnus successfully opens connection.

I dunno how to do it right now, but I'll try to figure out. Maybe using
tcpdump is the simplest...

Trying to open those groups didn't work somewhat differently, but now it
does, I think due to lesser number of messages:
85962: inbox.comp.lang.ruby.core
85958: inbox.comp.lang.ruby.dev

I think it's there for a long time, and only showed itself once a
group gets big enough.

No problem, thanks for looking at it!

That doesn't seem to be it, as it's still doesn't work, the same way as
before. I'll get back with protocol dump collected...
Thanks!

(any reason this wasn't sent to the public list? others may be
able to help if my 2nd attempt to fix did not work)
Anyways, I noticed you're pipelining a lot of XOVER commands and
maybe
https://public-inbox.org/meta/20180307190810.20784-1-e@80x24.org/raw
helps (deployed to news.public-inbox.org)
Otherwise, I also looked at the emacs source ( ./lisp/gnus/nntp.el )
and found:
(defvoo nntp-maximum-request 400
"*The maximum number of the requests sent to the NNTP server at one time.
If Emacs hangs up while retrieving headers, set the variable to a
lower value.")
Maybe you can set nntp-maximum-request to a smaller number
(maybe 5) and see if it helps.

The only reason is the presence of rather long attachment.

Apparently it does, as it now works without any intervention from my
part.
Thanks a lot!
