Michael Chen commented on CAMEL-2854:
-------------------------------------
Here how the route is built:
from("direct:UserCancelJobRequest").process(new Processor() {
public void process(Exchange exchange) throws Exception {
....
}
}).
to("direct:JobRunInstanceUpdate"). ...
We use dynamically constructed routing slip or template to send messages to the
"direct:UserCancelJobRequest" endpoint.
There should always be consumer for this. Otherwise Camel would be to
unpredictable to use. That is real bug that needs to be fixed.
Thanks

> Project: Apache Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.2.0
> Environment: ActiveMQ 5.3.2 / Camel 2.2.0
> Reporter: Michael Chen
> Assignee: Claus Ibsen
> Priority: Critical
> Fix For: 2.4.0

> The following warning in log4j log shows up with no predictable reason:
> 2010-06-24 14:07:01,090 WARN
> [DefaultMessageListenerContainer-7:DirectProducer.java:42] No consumers
> available on endpoint: Endpoint[direct://UserCancelJobRequest] to process:
> Exchange[JmsMessage:
> RunnerBase{locationToRunId='DV02YcABTE43HTRPATEGCBFk0m0', jobrun_id=1234,
> requestOrigId='null', secretKey='null', replyToQueueOrTopic='null',
> corrolationId='null', requestCreationTime=Thu Jun 24 14:07:01 PDT 2010}]
> The endpoint [direct://UserCancelJobRequest] could be a number of different
> endpoints in our application and all of them are of "direct:" type. When
> this happens, all messages that run through that endpoint will fail, and it
> will never recover unless the application is restarted.
> Also, if I restart the application and use that route immediately, that
> warning will not occur and the request will finish successfully. It seems to
> happen to routes that have not been used for a while after startup.
> When this happens, I can find the exact Camel endpoint/route/processor in
> JConsole, and nothing seems to be wrong. How can a "direct:" endpoint runs
> out of consumer? Isn't the thread that product this warning THE thread to
> process the message?
> We recently upgraded from 5.2 to 5.3.2 and this starts to show up randomly.
> It is a show stopper!
