Subject: [syslog-ng] message loss using multi-line-mode<br>
Date: Wed, May 18, 2016 15:58</div>
</div>

<div style="background-color:#FFFFFF">That was my original intent (to write a patch), but after looking at the code, I didn't think it would be a good idea (I used to code against syslog-ng back in the around the 3.1 days, but it appears the code has gotten
significantly more complex).<br>
<br>
Given that there is message loss involved here, I just thought it might raise the priority of the issue.<br>

I don't think that would help, sorry. Everyone is working on other stuff as it seems. Would you try to cook up a patch? I know it might intimidating at first, but you know it's all just code and computers :) not more complicated than a shell script. *<br>

[*] ok, a bit more complicated, but everyone has to start somewhere :)<br>

Using multi-line-mode without the multi-line-suffix option WILL result in message loss.<br>
When syslog-ng is running in multi-line-mode, it buffers multi-line messages until it sees the start of a new message. When it sees the start of a new message, it flushes the buffered message, and puts the first line of the new message in the buffer. However
if syslog-ng shuts down, or receives a SIGHUP (reload), any lines currently buffered are discarded. Given that syslog-ng can't stay running forever, and it will get shut down or SIGHUPd eventually, using this feature will result in messages getting lost.<br>
