Syslog-ng PE crashes using kafka() destination driver (4266630)

When using the kafka() destination driver Syslog-ng generates a lot of core dump files which fill the disk and Syslog-ng eventually stops working.

Product Defect

Workaround 1:

Disable the disk buffer if not required.

Workaround 2:

Add a file("/dev/null") destination to the problematic destination definition, that will mitigate the problem, while leaving the disk queue in place.

See example below (highlighted):

+++++++++++++++++++++++

destination d_kafka {

  kafka(

         client-lib-dir("/opt/syslog-ng/etc/kafka_2.11-2.1.1/libs")

         kafka-bootstrap-servers("prd01.prd.domain.org:6688,prd02.domain.org:6688)

         topic("${.kafka.topic.name}")

   disk-buffer(

            reliable(no)

            dir("/data/buffer/")

        )

        );

   file("/dev/null");

};
