static final long DEFAULT_SCAN_PERIOD_HOURS = 21*24L; // three weeks
but definitely it does not wake up and pick a
Brian,
When you say *attempt* to complete and *entire* node scan,
you mean for example, if a node has 100 block files, it will
try to verify all 100 block every 3 weeks?
That is in average, a block is scanned every (3 weeks / 100 time interval)?
