symious opened a new pull request #3090:
URL: https://github.com/apache/ozone/pull/3090


   ## What changes were proposed in this pull request?
   
   This bug was imported in 
[HDDS-6215](https://issues.apache.org/jira/browse/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`.
   ```
       conf.setLong(RECON_OM_DELTA_UPDATE_LIMIT, 2);
       conf.setLong(RECON_OM_DELTA_UPDATE_LOOP_LIMIT, 10);
   ```
   ## What is the link to the Apache JIRA

   unit test.
