Raúl Kripalani commented on CAMEL-9826:
---------------------------------------
Quick question. Have you seen this actually happening?
* The keepRunning flag is volatile.
* The cursor is closed by the shutdown thread, therefore the call to
`cursor.hasNext()` in the while guard should unblock and either give an
opportunity for the guard to evaluate the new value of keepRunning (false) or
throw an exception, unless there's a bug in the MongoDB driver and
`cursor.hasNext()` never returns even when another thread has closed the cursor.
> MongoDB consumer could potentially block during shutdown

> There is this endless while loop
> https://github.com/apache/camel/blob/master/components/camel-mongodb/src/main/java/org/apache/camel/component/mongodb/MongoDbTailingProcess.java#L132
> This should be using a CountDownLatch to await for the stop to complete so
> there is no endless while loop.
