How's your disk? Do you see many ext2 errors? yeah, a few there's some weird corrupted files in /var/spool/news/control, too: c---r- 1 8736 30054116, 32 Apr 4 1987 504023 cr-Sr-sr-x 1 115658224 32, 32 Jan 30 1987 504024 br-x-w 1 2674028270110, 105 Mar 21 2029 504027 br-xrt 1 1189128015108, 101 May 22 2031 504028 br-sr-srwx 1 2819328265112, 45 May 22 2031 504029 c---r- 1 2849930068 32, 101 Mar 30 2029 504048 br-xrwS--- 1 269948294 101, 109 Mar 9 2029 504049 br-xrwSr-- 1 1496228520104, 116 Nov 26 2023 504050 These can't be deleted, moved, chmod-ed, chattr-ed, or anything. Any attempt to do something to the files results in Operation not permitted (btw, this is what they look like AFTER running e2fsck on the partition - unmounted, of course - they used to have unreasonably large sizes before that...4gb and more) I'm going to reformat the drive when i have the time to bring the system down for a few hours. Trying to use MMAP on Linux Is this still true for linux? No. we are running INN with mmap() on on all our news servers (inn 1.4unoff4, linux-2.0.25 or so) and we have 5 feeds in totalling about 400 Mb/day, 30 or 40 feeds out (small ones like linux.* and a couple of full ones). OK, sounds good to me. Are any of these feeds uucp? My main newsfeed is uucp over a trailblazer modem - bandwidth is expensive here in australia and there's better things to use it for than usenet news. Has inn for debian been compiled with MMAP turned off? If not, should this be reported as a bug against inn? AFAIK, nobody has complained about this yet - however I have seen the same problem in the following cases: from what you say, it isn't a problem anyway. 1) rmgroup immideately followed by a makegroup control message (resets the counters to 0 but doesn't delete the articles) 2) Harddisk problems, especially 4Gb disks go bad very fast IME. i suspect that this is the likely cause. either the hard disk or the ide controller. it's a new quantum bigfoot, 2.5GB, on an ASUS SP3G PCI motherboard. The bigfoot drive only got put in a few months ago, to replace a seagate 1GB scsi drive (which was big, fast, and extremely noisy - the bigfoot is slower but bigger and wonderfully quiet) I used to get the same problem with the old seagate scsi drive, just not as often...which could be due to the fact that i'm now keeping news for twice as long. I've kludged a temporary fix. I run 'ctlinnd renumber' before and after news.daily in my fixnews.nightly script. My fixnews.weekly script rebuilds the history file and then runs fixnews.nightly. it's not a real fix, but it stops the error messages, and prevents /var/spool/news/.incoming from filling up with hundreds of megabytes of compressed rnews batches which inn cant process due to being throttled (news is very low priority - sometimes i dont notice theres a problem for a day or two). BTW, I'm not planning a 1.4unoff4-2 at this time (though I have one available) but instead I want inn1.5 in bo. Under Linux, it doesn't make much difference if you have mmap() on or off because the buffer cache is so good. If people prefere to have it turned off, that's no problem with me. 1.5 went out of beta just recently, i saw the release version on the ISC INN web page.

innd mmap
my news box is regularly throttling with the log message File exists writing symlinking article file -- throttling. I've found a relevant section in /usr/doc/news/inn-faq-5, which describes the problem and also has a fix (run 'ctlinnd renumber'), but this is only a patchup job...in a couple of days the problem has occured again. extract from the inn faq part 5: QUESTION: I'm running INN 1.4, and the server throttles itself, saying File exists writing symlinking article file -- throttling. Why? I have no clue, other than to note that the message is being emitted while innd/art.c tries to link a crossposted group. ANSWER: Innd wrote the article to comp/foo/123 and then tried to symlink it to alt/bar/128 and found that the symlink failed with errno == EEXIST. This generally only happens when your active file does not match your file/directory use. The three most common cases of that are: Trying to use MMAP on Ultrix Trying to use MMAP on Linux Some strange interaction with tind. If you are using Ultrix or Linux, turn off MMAP. You don't have a choice in this. The Ultrix mmap() function does something completely different than the Sun/BSD mmap() function. The Linux function gives you some of the functionality that Sun/BSD mmap() function has, but not enough. (The Linux people expect to have it fully up to spec eventually, yeah right.) Is this still true for linux? is it a kernel or a libc problem? Has inn for debian been compiled with MMAP turned off? If not, should this be reported as a bug against inn?
