[syslog-ng] unix-dgram for Linux syslog stream

[ZeroUno]

Hi,
I've read some old discussions about unix-dgram vs unix-stream for 
getting the /dev/log syslog stream on Linux (e.g. 
https://bugs.archlinux.org/task/22153), but some years have passed by 
and I'd like to be sure my configuration is safe.

I'm using syslog-ng 3.2.5 on a system composed of different Linux 
(RHEL6) machines. I cannot install a different version.
There is a central log facility, but each machine collects and sends its 
logs using the following source config:

source src {
	file ("/proc/kmsg" program_override("kernel: "));
	unix-dgram ("/dev/log" flags(no-multi-line));
	internal();
};

It was originally using unix-stream(), but I need to change it to 
unix-dgram() because some custom applications are sending multiline 
messages which need to be converted into single line, and unix-stream() 
does not support this flag.

Can I be sure that no messages risk to be lost due to this change?
This is a rather critical application.

Thank you very much.
