> The bug occurred because there was no check if rereplication was enabled or
> not when the auditor came online. When the auditor comes online it does a
> check of which bookies are up and marks the ledgers on missing bookies as
> underreplicated. In the false report case, the auditor was running after each
> bookie was bounced due to the way leader election for the auditor works. And
> since one bookie was down since you're bouncing the server, all ledgers on
> that bookie will get marked as underreplicated.
