Thanks!
I've created a follow-up ticket: CAMEL-7425.
> EventDrivenPollingConsumer can lose exchanges when the internal queue is full
> -----------------------------------------------------------------------------
>
> Key: CAMEL-7411
> URL: https://issues.apache.org/jira/browse/CAMEL-7411
> Project: Camel
> Issue Type: Bug
> Components: camel-core
> Affects Versions: 2.13.0
> Reporter: Benedikt Waldvogel
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 2.12.4, 2.13.1, 2.14.0
>
>
> The exchange processing in the {{EventDrivenPollingConsumer}} can lose
> exchanges when the internal queue is bounded and full.
> The implementation:
> {noformat}
> public void process(Exchange exchange) throws Exception {
> queue.offer(exchange);
> }
> {noformat}
> The reason is that {{BlockingQueue.offer(...)}} is non-blocking and returns a
> boolean which indicates whether the element was added.
> However, the return value is ignored causing the exchange to get lost if it
> could not be added.
> A potential workaround is to use an unbounded BlockingQueue (e.g.
> LinkedBlockingQueue).
