Rabbitmq Resource Locked - Cannot Obtain Exclusive Access To Locked Queue


This message is subject to terms available at the following link: http://www.ml.com/e-communications_terms/. Iam getting the following error when trying to resubscribe to the queue. [AMQP Heartbeat Inbound for Connection amqp-0-8://GBWMAPPROPP04.emea.win.ml.com:5672] ERROR MessagingManager.MessagingSubscriber SubscribeForMessage - OpIntEx: The AMQP operation was interrupted: AMQP close-reason, initiated References to "Merrill Lynch" are references to any company in the Merrill Lynch & Co., Inc. If a client can create both exclusive queues then it will be the UDP broadcaster. this contact form

When either peer detects 2 missed heartbeats, it should consider the connection to be dead. :heartbeat is the option passed to MarchHare.connect to configure the desired timeout interval. What I need to do is prevent both consuming applications from broadcasting the datagram on the target network. With Langohr, channel-level exceptions are raised as Java exceptions (IOException or ShutdownSignalException) that provide access to the underlying channel.close method information. Reader feedback is key to making the documentation better.

Maybe two applications or pieces of code declare the same entity with different attributes. AMQP::Session#after_recovery is similar except that the callback is run after AMQP connection is reopened. Ruby amqp gem 0.8.x and later lets applications define handlers that handle connection-level exceptions, channel-level exceptions and TCP connection failures. Full example (run it, then shut down AMQP broker running on localhost, then bring it back up and use management tools such as rabbitmqctl to see that queues, bindings and consumers

Because initial connection failures are due to misconfiguration or network outage, reconnection to the same endpoint (hostname, port, vhost combination) may result in the same issue over and over. For example, if a producing application sends messages every minute because of the nature of the work it is doing. In any case, your application should be prepared to handle this kind of error. What might cause it Multiple applications (or different pieces of code/threads/processes/routines within a single application) might try to declare queues with the same name as exclusive.

I guess that's probably not what you want.I would look to other means if I were you. Is the client naming the queue or is it getting the server to generate a name for it?

With RabbitMQ, when broker is stopped using rabbitmqctl stop reply_text will be set to CONNECTION_FORCED - broker forced connection closure with reason ‘shutdown’ Each application chooses how to handle graceful broker The Shutdown protocol revolves around two events: Network connection fails Broker closes AMQP connection (or channel) In this section, we will concentrate on the former. For example, if delivery tag = 5 that would mean “acknowledge messages 1, 2, 3, 4 and 5”. You must be doing something different though, since the RESOURCE_LOCKED error indicates that an attempt was made to re-declare the queue when it existed already, and from a different connection to

When a client comes up it will try to connect to each broker, if those connections succeed then an attempt is made to create an exclusive queue on each broker, no Automatic Recovery Many applications use the same recovery strategy that consists of the following steps: Re-open channels For each channel, re-declare exchanges (except for predefined ones) For each channel, re-declare queues There are two ways of detecting TCP connection failure, the first one is to catch an exception: begin AMQP.start(connection_settings) do |connectionnavigate here To exclusively receive messages from the queue, pass the “:exclusive” option to {AMQP::Queue#subscribe}: queue.subscribe(:exclusive => true) do |metadata, payload| # message handling logic...

A common technique is to combine Object#method and Method#to_proc and use object methods as error handlers: class ConnectionManager # # API # def connectgroup of companies, which are wholly-owned by Bank of America Corporation.

Where do I drop off a foot passenger in Calais (P&O)? Before a queue can be used, it has to be declared. Fortunately, the recovery process for many applications follows one simple scheme that Bunny can perform automatically for you. Not the answer you're looking for?

Network Connection Failures Detecting network connections is nearly useless if an application cannot recover from them. Exclusive queues are deleted when the connection goes away.
