I can't really apply that workaround to our application (deleting the
queue and re-creating it) I'm afraid.

We don't have any message expiry set so I don't think that is it.  FWIW
I tried 5.14.4 and the same problem seems to be present.

When I get some free time in the weeks ahead I'll see if I can reproduce
