[syslog-ng]reading debug output

I have syslog-ng (1.6.4) running as "syslog-ng -d -v" and I happen to know that messages are buffering up, because I defined a TCP endpoint where there's nothing listening. I can't tell from the debug output what the buffer looks like (how full it is), is it possible to tell or is there no way to know? Well, no way except failed connection messages on internal() and the eventual STATS messages telling of dropped messages of course.
