I upgraded an IBM Lotus Domino Server to Version 8.5 and configured it to use DAOS. As I used the compact task I saw this ugly error message:

01/27/2009 23:16:32 The database /home/domino01/data/common/smartup4.TMP was unable to write to file /home/domino01/DAOS/0001/462C1A5581296F54C125754B007A5D302462C1A5581296FP.nlo: Release 8.5HF23 December 31, 2008

I remembered I heard at Lotusphere that DAOS does not work when using 2048 bit server id-files so I added DAOS_ENCRYPT_NLO=0 to the notes.ini file. After a restart of the server DAOS is now working fine.
