  Well, that's not quite true. We found one at least one set of
  problems, which is that the logic for delayed mtime/atime updates was
  not pushing pending mtime/atime updates out. That I believe has been

  There was also another set of problems that came to light when someone

  the resolution of that was, if any.

I have applied last patches. Now, my server runs 7.0.1. Last night, after upgrading pkgsrc from CVS tree, I have seen "to many open files" and fs was currupted again. Some directories do not contains '.' or '..'.

legendre$ uname -a
NetBSD 7.0.1 NetBSD 7.0.1 (GENERIC.201605221355Z) amd64
legendre$ mount
/dev/raid0a on / type ffs (asynchronous, log, NFS exported, local)
/dev/raid0f on /var type ffs (asynchronous, log, local)
/dev/raid0e on /usr type ffs (local)
/dev/raid0g on /home type ffs (asynchronous, log, NFS exported, local)
kernfs on /kern type kernfs (local)
ptyfs on /dev/pts type ptyfs (local)
procfs on /proc type procfs (local)
tmpfs on /var/shm type tmpfs (local)

If I remove async from /etc/fstab, I obtain a fts_read error. With aync, error differs but result is the same. I have to reboot with fs in ro mode to run fsck.

	Best regards,
