# Description When using message extending feature together with Threads EIP, it was possible to completely block the consumer (deadlock) if the message extend executor task queue would be filled up. This could be triggered by the default threads profile where the message queue size is set to 1000 tasks. On default settings, the consumer would consume: `max queue size`+`max threads`+`consumer thread` = 1000+20+1 concurrent tasks. The extender queue size however is only 1000. The `consumer thread` is due to `CallerRuns` policy. There is no way to register that the consumer is called from a route which uses threads EIP, and thus we have two options for preventing this blocking behavior. Either increase the maxQueue size to something very high - or make it unbound. I went with the latter as I believe it to be safe as the queue will be constrained by the thread profile of the route at all times and thus cannot grow unbounded, except if the outer profile is configured without a limit. # Target - [x] I checked that the commit is targeting the correct branch (note that Camel 3 uses `camel-3.x`, whereas Camel 4 uses the `main` branch) # Tracking - [x] If this is a large change, bug fix, or code improvement, I checked there is a [JIRA issue](https://issues.apache.org/jira/browse/CAMEL) filed for the change (usually before you start working on it). <!-- # *Note*: trivial changes like, typos, minor documentation fixes and other small items do not require a JIRA issue.
