Matteo Merli commented on BOOKKEEPER-596:
-----------------------------------------

Looks like it's more than the set inclusive of the last ledger in the range. I 
think some range might me missing when doing the scan: 

I create 10001 ledgers (to span over 2 ranges : 00/0000 and 00/0001)

{code}
LedgerRangeIterator iterator = getLedgerManager().getLedgerRanges();
while (iterator.hasNext()) {
     LedgerRange ledgerRange = iterator.next();
     LOG.info("Found range: {}", ledgerRange.getLedgers());
}
{code}

but the iterator just gets the ledgers in the 00/0001 range

                
> Ledgers are gc'ed by mistake in MSLedgerManagerFactory.
