Fairly often (but not reliably reproducible), news hangs (throbber and status bar animations continue) while downloading messages on news1.sympatico.ca. It happens most often when an article that's been expired is requested, but also happens on other valid articles. A partial NNTP log is included here: 1024[80587e8]: Sending: GROUP alt.fan.harlan-ellison 1024[80587e8]: Next state: NNTP_RESPONSE 1024[80587e8]: Receiving: 211 25 24506 24540 alt.fan.harlan-ellison 1024[80587e8]: Next state: NNTP_SEND_GROUP_FOR_ARTICLE_RESPONSE 1024[80587e8]: Next state: NNTP_SEND_ARTICLE_NUMBER 1024[80587e8]: Sending: ARTICLE 24526 After 10 minutes or so, I got: 1024[80587e8]: Next state: NEWS_FREE Neither the message or an error is displayed during this time, and the message pane is "frozen" (i.e. it does not paint itself, just keeps the contents of any other windows that have been over it). I can navigate in the folder and thread panes, though. Navigating to another (expired) message, I get: 1024[80587e8]: Next state: SEND_FIRST_NNTP_COMMAND 1024[80587e8]: Next state: NNTP_SEND_GROUP_FOR_ARTICLE 1024[80587e8]: Sending: GROUP alt.fan.harlan-ellison 1024[80587e8]: Next state: NNTP_RESPONSE 1024[80587e8]: Receiving: 211 11 24528 24540 alt.fan.harlan-ellison 1024[80587e8]: Next state: NNTP_SEND_GROUP_FOR_ARTICLE_RESPONSE 1024[80587e8]: Next state: NNTP_SEND_ARTICLE_NUMBER 1024[80587e8]: Sending: ARTICLE 24523 1024[80587e8]: Next state: NNTP_RESPONSE 1024[80587e8]: Receiving: 423 No Such Article In Group 1024[80587e8]: Next state: SEND_FIRST_NNTP_COMMAND_RESPONSE 1024[80587e8]: Next state: NNTP_ERROR 1024[80587e8]: Next state: NEWS_FREE Sometimes I can navigate away from an unexpired message, then select it again and it will be retrieved. Other times it will remain unavailable for the session or across sessions. I always get a 423 return code if I try to view the expired articles myself, as with the second (successful) log excerpt above: > telnet news1.sympatico.ca 119 Trying 188.8.131.52...

Linux build 2000122710. Also, I don't have this problem at all reading news.mozilla.org.
Is this an especially slow server?
It doesn't seem to be--how would I go about measuring the speed? The Ellison group doesn't have any particularly large posts, so it shouldn't be timing out while retrieving them.
There doesn't seem to be anything out of the ordinary with your setup, so I can only assume there is some kind of underlying network issue here. I'll try it with that newsgroup on my P133 and see if I get any results.
Hrm, strange, this works fine for me (there was only 26 postings when I loaded this ng). I used RedHat 7, build 2001011208.
Sounds like it may be the Sympatico server, then. Any suggestions on debugging?
Not sure how much David or Seth know about Typhoon servers. Adding David to the list. Are you on dialup? What is the last build you tried this with?
I'm running 2001013108 on "high-speed" DSL. I haven't seen the problem as much recently (since the "only one download thread for news" bug was fixed), but it still occurs occasionally. There hasn't been as much traffic in the group recently though, and I'm not really subscribed to much else on that server--I'll try a couple of higher-traffic ng's and see if I see it more.
Okay, if you find an especially high traffic newsgroup, please post it here. They are very useful for stress testing!
Trying with a 500-message set of rec.arts.sf.tv.babylon5.moderated in build 2001020908, I've gotten a few "freezes", but they have gone away after selecting one or two messages, then returning to the "frozen" message. I've read about 250 messages and I'd say I've frozen on 15 of those; three occurred in a row, and the rest have been single occurrences. The freezes occurred, about 95% of the time, after I went back to a post I had already read (to see some thread context that wasn't quoted), then continued to the 'next unread'. Regarding the comment on the server being slow, I got about 1.5K/s downloading the list of newsgroups (on a 128K DSL connection). So I guess that's slow. :-) http://www.sympaticousers.org/ has some discussion of the poor news servers, but nothing specifically about performance.
Wow, hey Seth, take a look at this, http://www.sympaticousers.org/action/news_service.htm Looks like they have lots of issues with headers not being downloaded, etc.
Hmm, I must be reading that page differently. I thought it referred mostly to headers (and messages) not being synchronized between the different servers... although they do mention Netscape (I assume 4.x) having problems with out-of-order headers. I haven't seen any problems doing a header download when entering the newsgroups.
Oh, I haven't read the whole article (yet). I'm referring to the screenshots, where it shows "Warnings" next to Downloading news articles and "Failed" checking (what I assume to be) "Bell" a server for new messages. Notice, there don't seem to be any updated warning for this year, though it seems they've had their share of problems.
Here's a link to the type of server that your using: http://www.bcandid.com/discussion/service_providers/typhoon/typhoon_content.html
mozilla hangs sometimes/often when using leafnode as newsserver i think this bug is related to 63880 (or perhaps 58247) unfortunately it works if I connect directly to the news server (not using leafnode) and mozilla doesn't always hang if using leafnode. It only hangs on some groups but if it hangs it will always do. tried moving the msf file as described in bug 58247 but it still happened (the file was empty btw) unfortunately i don't know anything about the nntp protocol but i think mozilla is requesting the article with id 1 that doesn't exist on the server (doesn't exist in the leafnode spool directory) and perhaps this is the problem ? so i would say this is bug 63880 ? i coppied a news message (2) to 1 => now the requested message 1 exists => it works (unfortunately it seems mozilla doesn't know how many messages there are now but this is not related to this bug i think.) the problem doesn't occur with mozilla 0.8.0 or other nntp clients (pine/netscape, navigator 4.7?) another idea: perhaps it is a problem with "remove all expired articles" If mozilla hangs there is no network traffic and send and receive buffers are empty. Leafnode is waiting for incoming traffic. if you want i can add a lot of detail (gdb stacktrace , traffic sniffed, netstat, ...)

I reported the problem with leafnode. Since mozilla 0.9.3 it seems to be fixed?
Peter Janes, is this bug gone for you too, now?
I've only noticed "hangs" once or twice in the last month, and they're attributable to outside influences, so I'd say it's fixed.
Okay, marking as such. One of you guys please verify then (I'm not running a leafnode server, currently). Thanks.

verified. Two people's word is good enough for me (especially since Peter was the reporter).
