zfs arc eating up all memory

Hi all,
I kind of accidentialy did 'du -sh' on my homedir and forgot that I had
set snapdir=visible.
After some minutes wired memory growed from 2g to 7.5g, active memory
dropped from 700m to 20m and heavy swapping occured.
I was not able to reproduce this behavior in my test vm (i386 vbox) and
testing on the server is difficult, because I have only ssh access and
if I do not kill 'du' in time, I can only hard reset the system.
If I set snapdir=hidden there is no problem, even if i run 'du -sh /'
Reducing vfs.zfs.arc_max to 2048m did not solve the issue.
Any ideas/hints to solve or workaround this problem?
