I have compiled syslog-ng-1.9.5+20050730.tar.gz and it does not seems to 
work and it cannot open udp source.

Debugging with a single udp() source:

afsocket_sd_init (s=0x8067f38, cfg=0x8062a20, persist=0x0) at afsocket.c:403
self->connections = persist_config_fetch(persist, 
afsocket_sd_format_persist_name(self, FALSE));
self->connections is null due persist==0x0

afsocket.c:412
if (!(self->flags & AFSOCKET_KEEP_ALIVE) || !self->connections || 
!afsocket_open_s... bails out here
self->flags = 0x701, self->connection=null
self->flags & AFSOCKET_KEEP_ALIVE > 0, hmmm, udp keepalive?

Note that persist if set to NULL at main.c:372 by calling cfg_init(cfg, 
NULL)

If you need detailed program tracking I can make you one.
