Setting a record to passive for debugging purposes can be useful. But I
would be wary of setting such a monitoring record to passive
(un-processed) as its default state. This can potentially be confusing to
the operator or others looking at the data in the future. At minimum, I
would use the alarm state to flag the record as INVALID and make sure the
display manager indicates the alarm state.

What is to prevent the overload or the bus conflict from occuring at the
most critical time, i.e. when many things are changing and your scan rates
are all at their maximum?
