Right, I'vebuilt a new database and everything seemed fine for a while and
now I've got this message back. It is due to the index on one of our
tables getting messed up - at least, if we drop and recreate the index
everything is fine. What should I do to track down what is happening?
Compile with asserts, or run with specific logging? Any advice
appreciated!
