Hi folks,
I just upgraded a zfs server from 7.0-something to 7.2-stable and
hoped to
get rid of some minor instabilities I experienced every 6 months or
so.
Unfortunately, the new system crashed for the first time after only
a few
hours when copying some files via scp onto it.
I got a kernel panic which looked quite similar to the one reported
here
(kmem_map too small):

I have a dual cpu dual core opteron system with 4GB of RAM and a 3-
disk
raidz1. I took out the memory settings from loader.conf as suggested
in
UPDATING. I did not yet upgrade zpool nor zfs version (would that
help?).
Are there any known issues or any further hints what might cause the
crash? I copied the files again, but this time everything went fine.
Hmm. Do you use i386 or amd64? This panic is (was?) pretty common on
i386 before tuning, but... 4GB RAM and an Opteron should have you
running amd64, no?
