See the stress test panic called 'Ran out of "128 Bucket"
<http://people.FreeBSD.org/%7Epho/stress/log/cons210.html>' on the 6.2
todo list and my own latest test here:
http://www.maniacs.se/~junics/temp/vmstat-z.txt
This test was on a new 6.2-RC2 install with no zone limit tweaks nor any
sbsize limits in /etc/login.conf.
I just made a vm disk image with replication instructions, however Peter
Holm have replicated it with his own tools so i have not bothered with
it until now.

That problem is being worked on but won't be fixed for 6.2-REL.
Depending on how complex the fix winds up being it may be an Errata
candidate when the time comes.

Perhaps we should mention some known workarounds in the errata
documentation. E.g. raising nmbclusters limit, etc.?
