Morphium, could you tell me what OS you are running and which syslog server you 
are using?

Also, how did you get the data you added to the issue, is it from your syslog 
server or from a tool like wireshark? I'm interested in knowing what the 
separating characters are. the [...]

Hi,

I'm using Server 2008 R2 on the eventlog-to-syslog - side.
On the server side, it's rsyslog (on gentoo).
We already tried different log formats, this one looks best (standard syslog 
format).

The line I pasted is from the Server log itself, it looks like:

It looks like you're using some multiline feature, so thats why I wrote I would 
like to receive one Event per line :)

Thanks for your time!

Sorry for the delay. I recently rebuilt my system and have not gotten my test 
VMs back on this machine yet. If possible could you conduct a test using Kiwi 
Syslog Server. It's free and it's what I used to test it originally. Also, if 
you have wireshark available do a capture and see what is actually coming 
across the wire.

I did a check of the code and there is nothing unusual going on there. Each 
event should get its own packet unless Windows is doing some caching (which I 
highly doubt). I know when I tested it it worked as expected. If you don't have 
the ability to do the testing right now I will get my environment set up this 
weekend and check.

I don't really think this is related, but is your syslog server set to
expect UTF-8 messages?

Here is an output from tcpdump (2 packets). It looks to me like it is combining 
events in a single packet and seems to be using <29> or <27> to separate events.

Is this the expected behavior?

I also just verified that this only happens in TCP mode. There is no problem in 
udp mode.

I think I have an idea of the cause. I will take a look. The <##> you
see is the start of each syslog message.
