Severity: wishlist
We run more tests, and observed that pgrading the storage server to
Debian12(/bookwork solves the issue.
The storage server can be accessed through rdma from debian11 and 12.
That means, the problem occurs only when the storage server is on
debian11, the client is on debian11 mounted with proto=rdma.
This information is good enough for us, as we'll upgrade first the
storage server.
Another workaround is to switch to proto=tcp
As this issue (proto=rdma from debian12 client to debian11 server) is
difficult to fix and a workaround exists, I'll downgrade the severity.
