Hono 和 Ditto 已成功连接。但是当我尝试从 Hono 发送数据时，我会收到 503 - 服务不可用消息。
但是当我检查同上日志时。我超出了以下 AMQP 限制。

我不确定 AMQP:Resource limit exceeded 错误是什么意思？这会阻止我从 Hono 发送到 Ditto 吗？
如果我将所有这些都放在同上 Mongo 服务器中的 dbs 下面并再次创建新事物和连接，它会起作用吗？

编辑：我尝试在出现错误的同一服务器中再次连接 Eclipse Hono 和 Eclipse Ditto。
执行 curl commnad 时收到状态 201（已创建连接）消息。但是当我同时检查我的日志时，我收到了以下消息。
connectivity_1_ad306c4c315b | 2019-10-15T15:46:36.233449988Z 2019-10-15 17:46:36,233 WARN [] o.e.d.s.c.m.ConnectionActor akka://ditto-cluster/system/sharding/connection/12/test_co_nn_id_12/pa - Operation <connect> on connection <test_co_nn_id_12> failed due to ConnectionFailedException: Failed to connect JMS client:connection disallowed by local policy [condition = amqp:resource-limit-exceeded].
注意：当我在我的本地机器或不同的服务器上尝试这个时，它工作得很好。
