---------------------------------------------
Hi Oli,
Yes, that's possible. You can change the timeout in
etc/org.apache.felix.eventadmin.impl.EventAdmin.cfg:
{code:java}
org.apache.felix.eventadmin.Timeout=1000
{code}
But it means some events can be lost.
I'm working on topic size limit improvement on Felix EventAdmin (see
https://issues.apache.org/jira/browse/FELIX-6205).
> Kafka appender highly uses CPU when using non existing DNS server name

> 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.
