Today, I saw the following message on my Domino console
[0E88:005A-0FF4] 08.03.2016 17:19:01 The database d:\Domino\data\mail\ukrause.nsf was unable to open or read the file d:\DAOS\0002\97FC43BEED143800A6608E557BE888498DB9BC5100015B7C.nlo: File truncated – file may have been damaged
If you see such a message in your production environment, you should immediately find out
- what causes the damage?
- which note does the .nlo belong to?
In my case, the answer for the first one is: Anti Virus Software.
And here is, how I found the answer to the second on
If not already in place, set
Next trigger a console command
tell daosmgr LISTNLO MAP -V mail/ukrause.nsf
This will create a file listNLO.txt in you Domino data directory
Open the file and search for the .nlo file in question
You now have the noteId of the document that has a ticket to the damaged .nlo.
Use your favorite tool to find and open the document.
In my case, it was just a SPAM mail. So no worries. But if this happens in production, you should now go and find the ( hopefully intact ) nlo in your backup and restore it.
