kern/146528: [zfs] Severe memory leak in ZFS on i386

[Michel Le Cocq]

Hi every body, I upgrade my Freebsd 8.2-STABLE i386 to 9.0 i386.
   Intel(R) Atom(TM) CPU D510   @ 1.66GHz
   real memory  = 4294967296 (4096 MB)
   avail memory = 3127390208 (2982 MB)

I'm on a ZFS Root file systeme on 2 USB drive and 6 sata drive for
data. 

	# zpool list
	NAME    SIZE  ALLOC   FREE    CAP  DEDUP  HEALTH  ALTROOT
	data    931G   254G   677G    27%  1.00x  ONLINE  -
	stock  74.5G  12.4G  62.1G    16%  1.00x  ONLINE  -
	tank    696G   574G   122G    82%  1.00x  ONLINE  -
	zroot  3.66G  2.49G  1.17G    67%  1.00x  ONLINE  -

Before upgrade, I must use some mana things in my /boot/loader.conf

	vm.kmem_size="330M"
	vm.kmem_size_max="330M"
	vfs.zfs.arc_max="40M"
	vfs.zfs.vdev.cache.size="5M"
	
With this config my server was not so stable.

Some days it work perfectly, some others it freeze with kmem_malloc
kmem_map too small. 
Without this mana it freeze really often.

The thing which make me upgrade is that after one of this crash after
reboot it won't mount my data pool which was at 99% of his CAP. The
only way I find to boot is to disconnect the pools drive and export
it.

Now I'm on exactly the same host after upgrade to 9.0 and it seems to
work really really better (3 days up with out any trouble).
