This will occur after ever reboot if you put this database on ephemeral storage!  You can work around this by having your service init script touch the file before running master.

When I understand you well, I could also remove the database and create
an empty file before starting. As a work-arround.

My problem is that I use the version in Debian, what is not good
maintained at the moment. Cyrus-imap is removed from Debian testing last
year. This means that when nobody cares, Cyrus will not be in the next
Debian version. And also not in many other Linux distro's like Ubuntu.
The freeze is in Januar/Februar.

You will say: use the upstream version. But sorry, I have to worry about
many programs. My choice at the moment is to use software what's in
Debian. I am using Cyrus imap about 17 years now, but it's possible I
even have to switch to something else for this reason.

Much thanks for your support!

With regards,
Paul
