The discussion is on disappearing inodes from the news file system.
The inodes mysteriously disappears and can only be restored by doing
an fsck.

in article <548@jpusa1.UUCP>, news@jpusa1.UUCP (usenet) says:

On this machine: ICM3216 sysV.2.2 news_2.11.8 (I have not seen it
yet under patchlevel 11 or 12, but those have only been running for
a couple of weeks) the file system is not anywhere close to being full
when the inodes vanish (at least 10Mb to spare). Thus the bug is not
related to disk blocks being unavailable. This is verified with `df'
which reports, say, 15Mb free space and 0 free inodes.

Does anybody really know what causes this? Does it have to be a kernel
bug (which would be my guess) or could it be a fault in the news software.
