[syslog-ng] ECONNREFUSED on /dev/log

[Árpád Magosányi]

Hi!

"strace logger hello" output contains this line:
connect(3, {sa_family=AF_LOCAL, sun_path="/dev/log"}, 110) = -1
ECONNREFUSED (Connection refused)

I see logs in /dev/xconsole, just cannot emit a log line with logger.
What could be the cause?

additional info:

# cat /etc/syslog-ng/syslog-ng.conf

@include "scl.conf"
# First, set some global options.

      bad_hostname("^gconfd$");
};

       system();
       internal();

destination d_messages { file("/var/log/messages");};

destination d_xconsole { pipe("/dev/xconsole"); };

filter apache_log { program("apache"); };

destination d_vhost_gepnarancs { file("/var/log/vhost_gepnarancs"); };
filter f_gepnarancs { program("apache:php:gepnarancs") or
message("gepnarancs"); };
log { source(s_src); filter(f_gepnarancs);
destination(d_vhost_gepnarancs); };

log { source(s_src); destination(d_messages); };

log { source(s_src); filter(non_apache_log) ; destination(d_xconsole); };

log { source(s_src); filter(apache_log); destination(d_apache_console); };

log { source(s_src); destination(d_net); };
