Hi,
while upgrade is in progress and also after reboot the syslog-ng startup script logs this error message:
Configuring system logging...Error opening plugin module; module='examples', error='/usr/local/lib/syslog-ng/libexamples.so: Undefined symbol "random_choice_generator_parser"'
It seems to be only a cosmetic issue, everything is working. I'm using syslog-ng with a remote TLS target.
