Earlier this morning, I found the following entry in the servers log file:

23.03.2009 06:33:09   Error reading FolderModified time from header in database E:\mail\xxxxx.nsf. Run Fixup on the database.: Invalid Time or Date Encountered
23.03.2009 06:33:09   Error reading FolderModified time from header in database E:\mail\xxxxx.nsf. Run Fixup on the database.: Invalid Time or Date Encountered

I tried to run fixup -F -j on the database, but the error re-appeared at the next replication.  I assumed a problem with either document or design where @Created has a value that is “too far in the future” or so. But how to find this one (?) element in a database that is almost 10 GB of size ond holds 50.000 documents?

I opened the database with ScanEZ and did a search on all design and data documents ( @Created>[12/12/2009] ) and got one match.

As you can see in the screenshot,  “Created Initially” has a suspect value. I deleted the document from the database and the error does not occur any longer.

UPDATE: Seems that this is a known issue in 7.0.3 and has been fixed with 7.0.3FP1 ( http://www.badkey.com/db/blogsphere.nsf/d6plinks/JWIE-7LJUXW ) but I am running Domino 8.5. So I will open a PMR with IBM support …
