Patrick, without answering the question directly: could you please try out
http://download.rsyslog.com/rsyslog/rsyslog-1.19.7.tar.gz [**still not "real" 1.19.7 **] I've possibly seen one thing that could be the problem cause. Not sure, though. I'd deeply appreciate feedback if this version (uploaded right NOW) causes the problem to disappear. I am not sure if I have found it, but I'd like to conduct a quick test before going any further. Thus I've no detailed analysis.
