Here are the distributor replication logs:

In order to better understand the replication keys and the No MATCHING entry that appears in
the logs, Structured Query Language (SQL) queries are run for more information about all of the
loggers and distributors.

Here are the SQL queries:

Here are the SQL query results:

Notice that the recovery keys for Logger A and Distributor A are significantly further apart than is
expected and than that on side B. Furthermore, the most recent data on Distributor A
approximately matches the location of the missing data reports that were first observed. Also note
the discrepancy in the maximum RecoveryKey distance between the table from the queries and
the logs.

You can view the recovery table in order to determine the keys that are stored.

Here is the SQL query:

Here are the SQL query results:

In the output, you can see that Logger A appears EMPTY, with no recovery key. Since this data is
unexpected, you should then verify the data in the Logger A recovery table.

Here is the SQL query:

When this query is run, the results are blank, which indicates that there is no data in the recovery
table. At this point, you should reevaluate the registry entries. When the two sides are exported
and a comparison is made, the discrepancy is noticed.

Here are the registry entries for Logger A:

Here are the registry entries for Logger B:

As shown on Logger A, the Recovery Days value is set for 0x1e, which is the hexadecimal (HEX)
value for 30. On Logger B, the Days value is set for 0xe42, which is the HEX value for 3,650.
Upon further review with the default registry entries in the lab, this seems to be the issue. This also
matches the symptom of the issue, which occurs approximately once a month.

The cause of this behavior has been reproduced in our labs in two scenarios.

Scenario 1 - When you create a new logger, if a user has enabled the check box for "Display
Database Purge Configuration Steps", it shows the recovery retention value as 30 days. This in
turn updates the registry settings after saving.

Scenario 2 - When you delete a logger and recreate it, if a user has enabled the check box for
"Display Database Purge Configuration Steps", it shows the recovery retention value as 30 days.
This in turn updates the registry settings after saving.
