But when I stop cyrus, the db folder just contains the DB_CONFIG file and a 4 
byte "skipstamp" file. Nothing else. Just when cyrus is running, there are 
some files in it:

-rw-------  1 cyrus mail    24576  3. Aug 22:06 __db.001

I changed tlscache_db and duplicate_db to skiplist now:

# file /var/lib/imap/*.db
/var/lib/imap/annotations.db:  Cyrus skiplist DB
/var/lib/imap/deliver.db:      Cyrus skiplist DB
/var/lib/imap/mailboxes.db:    Cyrus skiplist DB
/var/lib/imap/tls_sessions.db: Cyrus skiplist DB

Yes. It's all fine. When I remove the files and do a reconstruct they are 
recreated and the IOERRORS are gone. On some mailboxes the never came back, on 
others they came back after hours or some days.
