> This bug was imported in HDDS-6215, the root cause is we used `dbUpdates.getData().size()` to accumulate the sequenceNumber. But these two terms are different, a DBUpdates with data size of 10 could have a difference of sequenceNumber of 30 or more.
>
> The bug can be reproduced by adding the following configurations and running `TestReconWithOzoneManager`.
> {code:java}
> conf.setLong(RECON_OM_DELTA_UPDATE_LIMIT, 2);
> conf.setLong(RECON_OM_DELTA_UPDATE_LOOP_LIMIT, 10); {code}
