Bleah. We're having problems here, and I don't see what could be causing the problem. What's happening is that there are *lots* of duplicate messages on our system each coming from a different neighbor but always with the same Message ID. This is very different from the normal problem where some site out there munges article IDs causing duplicate messages. The software is at v2.11.14, with no local changes, or at least none of any significance. We also run nntp v1.5, but without any of the patches either official or unofficial. This is all on a Sequent Symmetry running the latest version of Dynix. The system has been running on our Sequent w/o problems until recently.... Something which has been happening is that occasionally the file system fills up, so I kill of the nntpd's and do find /net/spool.news -type f -size 0 -exec rm {} \; expire -r expire -e 24 /usr/etc/nntpd to restart the system. At least once when this happened another person here did the actual work of killing nntpd's and cleaning up the system. He'd have done without the find and expire -r, and just gone with the other expire. When he did this the history file disappeared, I know it did because there was a few pieces of mail saying that it was gone but that corrective actions fixed it. So when I saw this I stopped all news stuff and did expire -r and so forth. But I haven't yet done anything to remove the duplicate files that are in the filesystem, so there are some duplicate entries in the history file. So first off. Why did the history file disappear? And why did it disappear more than once. Will removing the duplicate files & rebuilding the database fix things again so that we're not getting more duplicates? In other words, is the software getting confused when it receives back multiple records from the history file? There has been some recent noise (er.. messages) along these lines. One message from Erik Fair saying that if you had some duplicate entries in history that you were in trouble. (He gave a short script for checking, and didn't say anything beyond that). The other from someone asking why his history file was disappearing. (btw, Erik's message was on nntp-managers a couple of months ago, so maybe I shouldn't call it recent?). -- <-- David Herron; an MMDF guy <david@ms.uky.edu> <-- ska: David le casse\*' {rutgers,uunet}!ukma!david, david@UKMA.BITNET <-- <-- Controlled anarchy -- the essence of the net.
