Jean-Baptiste Onofré commented on KARAF-4753:
---------------------------------------------
That's correct, timeout is for blacklisting of event handler. It's just a way
to avoid "full" topic. However, if there's no event handler, the event should
be removed (as it's a topic so pub/sub pattern).
Let me check about that. Anyway, I'm improving this in Felix EventAdmin.

> If you add a DNS name for Kafka for a not existing server, the appender will
> result in a very high CPU usage (near to 100%).
> This will also be the case, when you define mutliple kafka server locations
> and if just one of the DNS names are not resolved.
