Is this an issue with the Kernel?


Yes, this is a known issue with some combinations of syslog-ng, glibc and kernel versions.

It is not very well documented, but there are references in the balabit site. This is just one example.

In Debian, set SYSLOGNG_OPTS="--no-caps" in /etc/default/syslog-ng to workaround this issue.
