Errr, does for me
$ sysctl -a | grep vfs.zfs.zio.use_uma
vfs.zfs.zio.use_uma: 1
Thats from 8.1-PRERELEASE on June 2nd.

Hello,
I'd like to add another instance of similar problems. I recently
updated my FreeBSD amd64 box with ZFS root and 8GB RAM from 8-STABLE
(as of Mar 1st) to 8.1-PRERELEASE (as of May 27th). After that, my
box started to crash every couple of days due to kmem_map too small.

You can try disabling ZIO_USE_UMA in sys/modules/zfs/Makefile
Comment out following line in that file:
CFLAGS+=-DZIO_USE_UMA
This should revert memory allocation method back to its previous mode.
Let us know whether it helps or not.

vm.kmem_size limitation has been this way for a pretty long time.
What's changed recently is that ZFS ARC now uses UMA for its memory
allocations. If I understand it correctly, this would make ARC's
memory use more efficient as allocated chunks will end up in a zone
tuned for allocations of partic

I do suspect something similar like that, and try to roll the kernel back too.
I was just fine with 8.0 with zfs-on-roo

Yes.
