Updating the ESK stack (elasticsearch, syslog-ng, kibana)
Updating syslog-ng from 3.12.1-2 to 3.13.2-1
I got stuck with syslog-ng exiting with
Error initializing message pipeline; plugin name='java', location='#buffer:2:3'
I tried several things, from playing around with the client_lib_dir setting up to reinstalling openjdk in version 8 and 9 and reinstalling syslog-ng-core and syslog--ng-mod-* packages.
Finally. I returned to syslog-ng 3.12.1-2.
As I would like to use syslog-ng 3.13.2-1, I wrote a message to the syslog-ng mailing list: https://lists.balabit.hu/pipermail/syslog-ng/2017-December/024207.html
I hope this protects you from wasting hours like I did.
