这个错误看着是服务端返回的，去broker的日志里面，看看服务端的报错消息是哪一行

@leizhiyuan
broker.log日志看起来没有啥问题

但在remote.log却存在报错信息。

PS：目前就是在broker.conf配置brokerIP1=ipv6地址，生产和消费数据后，查看改mq状态就会提示该报错
当brokerIP1=ipv4地址，这种情况就不会出现

应该是这行代码没有考虑ipv6的情况

    @Override
    public long getEarliestMessageTime() {
        long minPhyOffset = this.getMinPhyOffset();
        if (this.getCommitLog() instanceof DLedgerCommitLog) {
            minPhyOffset += DLedgerEntry.BODY_OFFSET;
        }
        final int size = MessageDecoder.MESSAGE_STORE_TIMESTAMP_POSITION + 8;
        return this.getCommitLog().pickupStoreTimestamp(minPhyOffset, size);
    }

这里的是56+8

 public long pickupStoreTimestamp(final long offset, final int size) {
        if (offset >= this.getMinOffset() && offset + size <= this.getMaxOffset()) {
            SelectMappedBufferResult result = this.getMessage(offset, size);
            if (null != result) {
                try {
                    int sysFlag = result.getByteBuffer().getInt(MessageDecoder.SYSFLAG_POSITION);
                    int bornhostLength = (sysFlag & MessageSysFlag.BORNHOST_V6_FLAG) == 0 ? 8 : 20;
                    int msgStoreTimePos = 4 + 4 + 4 + 4 + 4 + 8 + 8 + 4 + 8 + bornhostLength;
                    return result.getByteBuffer().getLong(msgStoreTimePos);
                } finally {
                    result.release();
                }
            }
        }

        return -1;
    }

里面如果是ipv4，获取的是56:56+8（long）
如果是ipv6，就会越界，要获取68:68+8

@leizhiyuan 下个版本应该包含该问题的解决吧
