Hello Bernd, I've seen this behavior as well, in our case with Lustre 2.10.6+patches and zfs-0.7.11+patches. I'm looking into it, but do not yet have any more information.

The threads locks up the cpu and were killed after 22 sec, please have a look at the attachement. Is this a known problem and is this a zfs problem?
