Thanks for the info. I have seen your previous posts and the issues
do look very similar. A question for you, do the indexes that go
corrupt on you always seem to include at least one (usually more)
foreign key with poor selectivity? I have been looking back through
the logs on the various sites and this seems to be a common factor.
