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? -- Sergey ^ permalink raw reply [flat|nested] 6+ messages in thread

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? > 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 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 > 341199: inbox.comp.version-control.git OK, 341199 looks reasonable. > 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? 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. ^ permalink raw reply [flat|nested] 6+ messages in thread

I just deployed this RFC on news.public-inbox.org and hope it improves things: https://public-inbox.org/meta/20180307095222.18699-1-e@80x24.org/raw > Fwiw, I might not be online much the next few days.

I dunno how to do it right now, but I'll try to figure out.

No problem, thanks for looking at it!

I'll get back with protocol dump collected... Thanks! -- Sergey ^ permalink raw reply [flat|nested] 6+ messages in thread

(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. ^ permalink raw reply [flat|nested] 6+ messages in thread
