Hi,
I've tested it in a 8.3R jail on a 9.1R host, same setup, and the problem is
still there. So it may be a kernel bug on 9.1R.

I just checked in a change to HEAD (247814) that compiles CTL in GENERIC
but disables it by default. (i.e. it uses no memory) You can re-enable
it with the existing loader tunable.
i.e. set kern.cam.ctl.disable=0 in /boot/loader.conf and it will be
enabled.

Hey,
The GNATS database can now be mirrored using rsync from:
rsync://bit0.us-west.freebsd.org/FreeBSD-bit/gnats/
I expect that URL to be permanent, at least while GNATS is still
alive. At a later point there
Well now this is interesting.
I have converted a significant number of filesystems to ZFS over the
last week or so and have noted a few things. A couple of them aren't so
good.
The subject machine in question has 12GB of RAM and dual Xeon
5500-series processors. It also has an ARECA 1680ix in

What does zfs-stats -a show when your having the stall issue?
You can also use zfs iostats to show individual disk iostats
which may help identify a single failing disk e.g.
zpool iostat -v 1
Also have you investigated which of the two sysctls you changed
fixed it or does it require both?
You might want to try:-

Be warned it doesn't do any validation so if you use it against physical
interfaces with a smaller MTU things will likely go badly wrong, hell
they may go badly wrong anyway as its just a very quick and dirty
I get stalls with 256GB of RAM with arc_max=64G (my limit is usually 25%
) on a 64 core system with 20 new 3TB Seagate disks under LSI2008 chips
without much load. Interestingly pbzip2 consistently created a problem
on a volume whereas gzip does not.
Here, stalls happen across several systems
