So just for fun I tried this.. ;-) I did a destroydb on a database with 2
active backends and only 90 megs of data, and it managed to munge through the
other running database, which is fast approaching 2 gigs, in short order. The
first time I did it, I was able to rescue the second database just using the
audit trails that I'd built into it, but the second time it completely trashed
it. Now I'm no programming neophyte, but can somebody explain to me why this
happened? What exactly is destroydb doing, or am I missing something obvious here?
