Hi Pawel,

Thanks for you excellent work on ZFS!

I want to report that I got again a kmem_map_too_small panic on recent  
- - -current with the new ZFS version.
I left the machine overnight with an endless loop running bonnie++ on  
a raidz2 zfs pool with five disks,
and I found it dead this morning.
Is this still supposed to happen?

I had only these two lines in my loader.conf :

  vm.kmem_size="1536M"
  vm.kmem_size_max="1536M"

and i have just added vfs.zfs.arc_max="768M" and will
run the torture test again. (the default value for arc_max was  
1006632960)

Btw, the machine is amd64 with four gigabytes of RAM, and I have  
upgraded the pool to version 13.


Thanks!
