Multiple RabbitSubscribe in one class, one looses connection

[wodka]

We have a class similar to this:

class Message {
  @RabbitSubscribe({
    exchange: 'message',
    queue: 'message-a-queue',
    queueOptions: {
      durable: true,
      maxPriority: 10,
    },
    routingKey: 'message-a',
  })
  async handleA() {}

  @RabbitSubscribe({
    exchange: 'message',
    queue: 'message-b-queue',
    queueOptions: {
      durable: true,
      maxPriority: 10,
    },
    routingKey: 'message-b',
  })
  async handleB() {}
}

after a few days running then message-a-queue consumer disconnects! There is nothing logged and I have no clue how to debug this. To me it looks like only the later one reconnects.

Same problem!

Same for me -_-

@wodka Could you provide a small repo (the same exact golevelup modules version) so that we can see what's going on?

[wodka]

I can try - problem is that this is only happening after running for a few days :/

I believe there must be something that the module router that we have read might be throwing in which case the connection might be killed and not re-connected but I'd like to see if at some point I can play around with your repro and kinda attempt to force one handler to go down. If at some point you can give us more context, that would be great but feel free to create the repro when you can

[EvgeniLeonti]

we have a similar setup and also experience similar issues, in our case: this.amqpConnection.publish('EVENT_QUEUE', 'tx-created', {...}); throws an error

throw new Error('AMQP connection is not available');
/app/node_modules/@golevelup/nestjs-rabbitmq/lib/amqp/connection.js:192

this causes nestjs service to restart (if no catch handler exists) and seems like there has been a memory leak since then.

:/ trying to get it to reproduce I've now found one problem that was earlier not logged:

Error: Channel closed by server: 404 (NOT-FOUND)

-> the Channel exits and is filling and with a restart of the service process the entries...
