Domino 11.0 introduced web authentication via IDVault (and / or Directory)
Customers noticed large growing DDM databases and also flooding of console messages with error messages:
[0594:0013-1CE8] 10.08.2022 07:00:01 Event: Error adding event document to Domino Domain Monitoring: Event correlation cache is full. You can increase its size via the NOTES.INI setting EVENT_CORRELATION_POOL_SIZE.
[0594:0013-1CE8] Event correlation cache is full, too many Event documents in DDM.NSF for this server. You can increase the cache size by setting the EVENT_CORRELATION_POOL_SIZE setting in NOTES.INI. Default size is 73.400.320 bytes. Maximum size is 104.857.600 bytes.
After creating a case (CS0346074) with HCL-Support no suitable solution was found.
Creating a DDM filter or changing the authentication is not a suitable option. Excluding users from the Security-Policy with IDVault did not solve the issue.
=> It should be possible to exclude users (direct and via group) from the IDVault authentication mechanism, or create a logic that will only authenticate vaulted users with the IDVault. All others should use "directory" authentication.
If you check the history above mentioned case# the support found the root cause of the above DDM errors are caused by the failed IDVault authentication attempts, which are logged to DDM.

How come you are assuming that this console message has anything to do with the IDVault?
