Michael, this kind of corruption more often occures when FB server
is interrupted (crashed, unloaded, killed via Task Manager, power/OS
failure) doing garbage collection. There were unchecked reports that
sometimes it occures when sweep is activated on heavy loaded by user
activity server. So I recommend set sweep interval to 0 and include
sweep into your sheduled task which make backup in time of low users
activity.
