just wanted to report back that the strace/lsof/config is very useful. I've started to analyze the problem, and it is not related to flow-control, but rather
it seems to be related to the facts that:
1) writer side of syslog-ng has a higher priority
2) for some reason syslog-ng assumes that the writer fd is writable, even though it doesn't validate this claim using poll.
In the program() destination I cannot see how that could happen. This is where I stand right now.
I can hopefully close this issue on the coming weekend.
Thanks for your patience.
