[syslog-ng] syslog-ng running but not writing logs

[buckingham at nym.hush.com]

Hello forum members,

Having spent a couple of  weeks on this problem I thought someone
might be able to help getting  syslog-ng 3.9.1 to write log files on 
OpenBSD 6.2.

The O/S was a fresh install, then syslog-ng and lastly  BIND. No other
packages except syslog-ng and BIND dependencies have been  installed.
No binaries or libs from BIND conflict or replace any from  the
syslog-ng installation.
 The .conf file was copied over from an older OpenBSD system, also
running an  older WORKING syslog-ng (3.1.1). The required changes to
the .conf were made so  that syslog-ng 3.9.1 with supervisor starts
and remains running. By killing  the syslog-ng process I was able to
test that the supervisor process  restarts syslog-ng. The rc.d script
starts, stops and restarts syslog-ng  as expected.
/usr/local/sbin/syslog-ng -s returns no errors, indicating  that the
config file is sane.

In /var/log the only thing it  writes are syslog-ng start/stop
messages. In an effort to localise the  problem, a stub syslog-ng.conf
was created with the following contents:
	@version: 3.9.1 source s_local {         unix-dgram("/dev/log");     
   }; # destination catchall { file(/var/log/catchall); }; log {
source(s_local);  destination(catchall);  };
The  permissions and ownership on /var, /var/log, /var/run, and /etc
are  correct according to the OpenBSD /etc/mtree/special file. 
Syslog-ng starts retaining  root permissions (default) and creates
/dev/log if it does not  exist. The syslog_ng_flags I use are:
	"-R /var/run/syslog_ng.persist -c /var/run/syslog_ng.ctl -p
/var/run/syslog_ng.pid"Have tried running without any flags to see if
that would help, but did not help.

The output of syslog-ng -V is:
	syslog-ng 3.9.1 Installer-Version: 3.9.1 Revision: Module-Directory:
/usr/local/lib/syslog-ng Module-Path: /usr/local/lib/syslog-ng

On my hunt I foud a message on NARKIVE where a user was having the
same  problem with syslog-ng 3.6 on OpenBSD 5.9, there was no
solution. There  was a reply saying: "With the changes in 5.6 using
sendsyslog(2), only  syslogd picks up local syslog. Search the
openbsd-ports list for  syslog-ng to see some comments on it.".

 After a further search I turned up  nothing that would help.

Have also tried to compile syslog-ng 3.12 from source to see if that
might help solve the problem, but no success on OpenBSD.
 Many thanks in advance.
