I figured out that my disk was full. So this happens especially/only when the 
pool is full.

Yes, there are a number of issues when a ZFS pool gets full which can lead to 
system instability. Was this on an expanding drive image on an HFS that got 
full, or was the ZFS drive full? The only way to recover in such situations is 
to have a snapshot which you can delete and save space.

We should probably document this issue on the wiki.
