> When the same non-existing object is requested from multiple connections (for
> example, on receiving multiple link attach performatives) and matching
> auto-creation policy creates the object, the failures can be reported for
> some of the incoming requests due to {{DuplicateNameException}}.
> The stack trace like the one below can be reported into the broker logs for
> the impacted connections:
> {noformat}
