ctl_cyrusdb - DBERROR db4

[Torsten Bunde]

Hi @all,

I've got a question about Cyrus where I didn't even find a solution with
google, etc. until now.

We are using a Cyrus server here that causes some problems sometimes and
we don't know why. We are able to repair this but we would like to know
why this happens.

We are using

- SUSE Linux Enterprise Server 9
- Cyrus 2.2.3

The first problem is, that there are sometimes database errors because
of wrong user rights. After a rotation the user cyrus is not allowed to
write in same files because they are owned by root. But this is not the
main problem.

Today in the morning the server logfiles had the following messages

Jan 17 06:00:01 zeus ctl_cyrusdb[5101]: DBERROR db4: Log sequence error:

Does anyone has any idea what happened here?

Thanks
