> 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}
> INFO [IO-/0:0:0:0:0:0:0:1:35050] (o.a.q.s.v.AbstractVirtualHost) - Unable to auto create a node named foo due to exception
