IIRC the Kafka Appender and asynchronous components don't like each 
other. The Kafka client library uses asynchronous calls and the Kafka 
asynchronous thread also generates log events. This can end up in 
problems like #2893[1].

When it comes to the Kafka Appender, I think a big rewrite is needed.
