Sequence number

Hello, im tracking the sequence numbers while subscribing to the whole market for Tokyo, Market_by_price. From my observations I can see that each subsequent sequence number is incremented by 16 untill ~36500, then starts again from zero. However ever now and then I get a skip or a jump. See Below:

2017-01-24 08:00:11.717 8411.T: BAD SEQ NUM, Expected:33696, Received:33695, Diff:-1 2017-01-24 08:00:13.984 8411.T: BAD SEQ NUM, Expected:33711, Received:33680, Diff:-31 2017-01-24 08:00:14.316 8411.T: BAD SEQ NUM, Expected:33696, Received:33695, Diff:-1 2017-01-24 08:00:14.676 8411.T: BAD SEQ NUM, Expected:33711, Received:33696, Diff:-15

Can you please explain what is happening here? Should I just discard some? are they partial updates? duplicates? reissues?
