      Description

      The customer reports that a changelog search of:

      (&(objectClass=*)(changeNumber>=1983470)(changeNumber<=1983472)))

      which should return 3 changes, only returns the 1983470 and 1983472 changes. However, this changelog search:

      &(objectclass=*)(changeNumber=1983471))

      returns the missing change.

       

      Adding some custom debug code to ChangelogBackend.findReplicaUpdateMessage() shows that we call the method with 3 different CSNs, but for the second CSN the replicaUpdatesCursor seems to look at the wrong database.

      method={findReplicaUpdateMessage(ChangelogBackend.java:1094)} starts for 00000160702b92cb187400002365 (6260)
method={findReplicaUpdateMessage(ChangelogBackend.java:1112)} ends after 1 searching {6260=1} with found for 00000160702b92cb187400002365
method={findReplicaUpdateMessage(ChangelogBackend.java:1094)} starts for 00000160702b92c92d7a000046f6 (11642)
method={findReplicaUpdateMessage(ChangelogBackend.java:1105)} ends after 1 searching {6260=1} with null for 00000160702b92c92d7a000046f6
method={findReplicaUpdateMessage(ChangelogBackend.java:1094)} starts for 00000160702b92cb187400002366 (6260)
method={findReplicaUpdateMessage(ChangelogBackend.java:1112)} ends after 1 searching {6260=1} with found for 00000160702b92cb187400002366

      The return "with null" is this case in findReplicaUpdateMessage():

                  if (compareIndexWithUpdateMsg < 0) {
                // Either update message has been purged or baseDN has been removed from changelogDB,
                // ignore current index record and go to the next one
                return null;
