The IPC id is clearly wrong, as you can see by the ???-ID part. Still, the
sys_bind interception looks fine.
I will test syslog-ng soon, maybe I can reproduce the error.

Whenever you get a message like rsbac_get_attr returned error xy and you are
not in soft mode, you can regard this as an error to be reported here. Any
error message that looks like an internal one should be reported.

I could setup a second mailing list rsbac-howto, where this could be discussed
separately. On the other hand, you could simply ask here.
The examples page is meant to be filled with all different sorts of examples
for more complex ideas. It is probably time to start a howto page that contains
help for single daemons.
