unexpected pageaddr

Hi Chaps,

I'm doing my usual pull-the-plug tests on some new servers, and I'm seeing this in the logs during redo. Is this in any
waynormal? I'm guessing it is because it's just under "LOG" rather than something like "WARNING", but I'm not taking
anychances. 

I've got disk caches off, fsync on and some new fangled Zero-Maintenance Cache Protection.

These machines are pretty much identical to our current machines, differences are 8.4 rather than 8.3 and ZMCP rather
thanstandard BBU.
