[syslog-ng] 3.0.3: Accessing unix-dgram source appears to break all logging

But who and what is reading the fifo /tmp/.tivoli/.logfile. in your configuration? Opening a fifo for write will hang until someone else opens it for read, that's how named pipes work...

Hello list,

my first post to the list, so hello everybody! :-)  I'm on Ubuntu 8.04.2
amd64 and trying to upgrade from syslog-ng 2.0.9-1ubuntu1 to syslog-ng
3.0.3. I've both tried the on balabit.com provided amd64 .deb package and
also created an own amd64 .deb with the default settings in /debian using
dpkg buildpackage.

I have the following two sources in my config:

source s_all { internal(); unix-stream("/dev/log"); file("/proc/kmsg"
program_override("kernel: ")); };

source src { internal(); unix-dgram("/dev/log"); file("/proc/kmsg"
program_override("kernel: ")); };

Logging works just fine with the s_all source. However, as soon as I
access the src source, by, for example

destination temp_logfile { fifo("/tmp/.tivoli/.logfile."); };
log { source(src); destination(temp_logfile); };

all logging will cease. Meaning, other than

Aug  5 15:04:23 server syslog-ng[17505]: syslog-ng starting up;

I'm not getting *anything* in my logs after restarting syslog-ng. If I
then comment destination temp_logfile ... again and restart syslog-ng,
logging works again.

The exact same config has worked just fine with 2.0.9-1ubuntu1.

Any idea what could be wrong here?

Thanks a lot!

Best regards
