My DFSR diagnostic report showed a 11003 warning. I found a few files in the PreExisting folder with a last modified date of yesterday.
The thing is initial replication finished months ago so I don't understand why new files were added to the PreExisting folder.
Search for 4002 events on the DFSR server reporting this warning to see if another initial replication took place, but didn't find any.
I then searched for 2202 and 2204 events to confirm if this was a journal wrap issue, but did not find any.
What else could it be?
