By the way, the exact build on the balancer is:

NS9.2: Build, Date: Jan 19 2011, 11:55:08

It worked fine for about 9 hours before it locked up, it worked fine for
another 9 hours or so after it locked up before we the vendor fingered
the cause and we took it out of service.

During the time that it was up, we did see a number of hits from
apparently native v6 users (T-Mobile android phones, for example).
