Ah.. perhaps the light begins to clear. I think I must have misinterpreted what the keep-alive option really does. I had thought it avoided re-opening a listener on the same socket on SIGHUP. From your reply, I'm now assme that all it does is ensure that 'ephemeral' connections accept()'ed from a listener are left open across a SIGHUP even if the listener is taken away. Is this nearer the truth? In which case , as you say, my patch is irrelevant to my real desire to avoid a re-open of any given listener ( of potentially any flavour ) across a SIGHUP, and the previous post about repairing the 'broken' glibc/syslog() call across a re-opened Unix DGRAM socket potentially provides an easier fix than a rewrite of syslog-ng. And/or avoiding use of Unix DGRAM sockets at all on glibc platforms until such a fix is in place.
