Is it with the Erlang client across an AMQP network link? Or some other client across an AMQP network link? Or is it with the Erlang client in the same Erlang cluster as the server?<br>
<br>If it's across an AMQP network link, perhaps you could paste in tcpdump output showing the bytes sent on the wire during the queue.declare. That way it's crystal clear what's happening.<br><br>If it's not across an AMQP link then yeah, perhaps the Erlang client needs more type-assertionish things in it :-)<br>

<div>Hi Tony,</div><div><br></div><div>I didn't save the scene, didn't really look into the fault client code.</div><div><div>Just had a quick test, reproduced by using term_to_binary instead of list_to_binary to make the queue name in Erlang client.</div>
<div>Perhaps this WAS exactly the case from the other day. shame :)</div><div><div>I simply though it was UTF used in that case because the crash report has "utf" in it.</div></div><div><br></div></div><div><a href="http://localhost:55672/#/queues" target="_blank">http://localhost:55672/#/queues</a></div>

The other day, we accidentally created queues and bindings with UTF characters in the names.<div>Then the management web GUI crashed (on mochiweb level if i remember correctly), so we couldn't delete the queu on GUI.</div>
