---------------------------------------------

I'm not able to reproduce the issue. Can you please provide a simple test case and eventually attach a thread dump ?

Thanks !

> 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.
