Ivan Kelly commented on BOOKKEEPER-596:
---------------------------------------

Added this test in GcLedgersTest.java 
{code}
    @Test
    public void testManyLedgers() throws Exception {
        final SortedSet<Long> createdLedgers = 
Collections.synchronizedSortedSet(new TreeSet<Long>());
        createLedgers(30001, createdLedgers);

        LedgerManager.LedgerRangeIterator iterator = 
getLedgerManager().getLedgerRanges();
        while (iterator.hasNext()) {
            LedgerManager.LedgerRange ledgerRange = iterator.next();
            LOG.info("Found range: {}", ledgerRange.getLedgers());
        }
    }
{code}
This should give 4 ranges. it only gives one.
                
> Ledgers are gc'ed by mistake in MSLedgerManagerFactory.
