[jira] [Created] (KARAF-4753) Kafka appender highly uses CPU when using non existing DNS server name

Jean-Baptiste Onofré created KARAF-4753:
-------------------------------------------

             Summary: Kafka appender highly uses CPU when using non existing DNS server name
                 Key: KARAF-4753
                 URL: https://issues.apache.org/jira/browse/KARAF-4753
             Project: Karaf
          Issue Type: Bug
          Components: decanter
            Reporter: Jean-Baptiste Onofré
            Assignee: Jean-Baptiste Onofré
            Priority: Minor
             Fix For: decanter-1.3.0


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.
