What to do if DAOS does not work properly after upgrading to Domino 11

After upgrading some of our mail servers to Domino version 11.0.1 we run into serious problems with DAOS. After upgrading from Domino 10.0.1FP3 to 11.0.1 on RHEL7, DAOS no longer worked correctly and DBMT moved all attachments back into the mail, which of course required a lot more disk space and backup volume. First measure was to stop DBMT to prevent further movement. All measures we had taken like rebuilding the DAOS catalog did not help.
