s5ialloc under ISC 2.2

[William Miskovetz]

I awoke this morning to a file system that was a little corrupt.  My
console had the following on it:

NOTICE: s5ialloc: inode was already allocated.

An fsck fixed up my file system (after removing some files that had
been trashed), but I'm wondering if anyone knows what would cause this
error.

I'm running ISC 2.2 on a Compaq 386/20.  9MB RAM, Maxtor 8760E, Adaptec
2322B-8 disk controller, 80387.  In general the system is pretty stable,
but periodically I get a corrupt file system (usually new's expire program
complains that it can't read a directory, and that directory has often
changed into an empty file).  I have plenty of free inodes if it matters.

If anyone has any ideas on what would cause this error, or what I can
do to fix it (enlarge kernel tables, etc.) I'd appreciate it.  Thanks.
