Ceph Octopus RGW 15.2.17 - files not available in rados while still in bucket index

Cheers everybody,

I had this issue some time ago, and we though it was fixed, but it seems to
happen again.
We have files, that get uploaded by one of our customer, only available in
the index, but not in the rados.

At first we thought this might be a bug (
https://tracker.ceph.com/issues/54528) which got fixed with the last
pointrelease, but it seems not. And only on customer got this problem. At
the moment we thing it is some very weird usage of the s3 API (they
developed their own library and used the AWS SDK for .net as a basis)
together with multipart uploads.

I am also not sure HOW they do the upload, because it is a backup that get
uploaded every day and they seem to have multiple of them. I didn't went
through all of our logs, but I managed to pull one lifecycle of a file from
the logs and it showed very strange errors at the end and I couldn't find
anything with this error.

Hope someone can tell me what this is and how I can fix it.

Cheers
 Boris
