> RabbitMQ Producer/Consumer does not recover if exchange/queue is deleted
> manually
> ---------------------------------------------------------------------------------
>
> Key: CAMEL-11791
> URL: https://issues.apache.org/jira/browse/CAMEL-11791
> Project: Camel
> Issue Type: Bug
> Components: camel-rabbitmq
> Affects Versions: 2.19.2
> Reporter: Hector Veiga
>
> While trying different recovering scenarios with camel-rabbitmq we tried to
> delete the exchange where the producer was sending RabbitMQ messages to.
> We observed that the exchange was never recreated again as well as no new
> channel were created in the channel pool. Every time a channel was used to
> send a non-existent exchange, the channel was closed and we got a log saying
> "Got a closed channel from the pool". Once it ran out of channels in the
> pool, we keep getting the same exception when a new message tries to be sent
> to the exchange:
> {noformat}
> Caused by: java.util.NoSuchElementException: Timeout waiting for idle object
> at
> org.apache.commons.pool.impl.GenericObjectPool.borrowObject(GenericObjectPool.java:1174)
> ~[commons-pool-1.6.jar:1.6]
> {noformat}
> We are using a InOnly producer and the options we are using are:
> {noformat}
> rabbitmq://somehose:someport/some_exchange?username=SomeApp&password=SomeApp&skipQueueDeclare=true&exchangeType=headers&automaticRecoveryEnabled=true&topologyRecoveryEnabled=true
> {noformat}
> It seems the code never catches a Exception thrown by
> channel.basicPublish(...) in RabbitMQMessagePublisher. Maybe we could catch
> if the issue is that the exchange got deleted and run the exchange
> declaration again?
