Shit, what have I done... of course the files
mentioned here do correspond to ext2 (Linux stuff),
and _not_ to UFS2.
The answer is in /usr/src/sys/sys/syslimits.h where
we find the following definition:
#define LINK_MAX 32767 /* max file link count */
Can you check _that_ number against the amount of
directories created?
By the way, in cases like this it's helpful if you
provide the _command_ that you tried and the current
directory from _where_ you've tried it.
Also see /usr/src/sys/ufs/ufs/ufs_vnops.c, lines 1748
and onward, to see the UFS mkdir() system call acting
with
if ((nlink_t)dp->i_nlink >= LINK_MAX) {
error = EMLINK;
goto out;
}
when the LINK_MAX limit is reached.
Sorry for the confusion.
