This message is not an issue you must address, syslog-ng by default opt
in using linux capabilities, but it cannot always use them (do not have
the capability to set capabilities).

Depending on that you want to use capibilities or not,

you can disable the default behavior of syslog-ng by providing a command
line option syslog-ng ... --no-caps

If you wish to use the capabilities, you also have to adjust
docker/kubernetes for enabling those capabilities.

Both docker, kubernetes and syslog-ng administrator guide is a good
starting point.

This error message won't prevent syslog-ng from running and working as
long as it does not really require those extra permissions.
If it requires, in those case you likely see other error messages about
permission issues.
