Hi Alex!<br>
<br>
I've checked the attached config and logs, and it looks like syslog-ng cannot send logs to the "/dev/uds_log" destination, and<span style="color: rgb(0, 0, 0); font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 11pt;"> you have flow-control enabled
in the config.</span></div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
Once you fill the disk-buffer (which is a 4MiB sized reliable disk-buffer), flow-control kicks in and syslog-ng stops reading more messages from the sources that are connected to this destination.</div>
<div style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 11pt; color: rgb(0, 0, 0);">
<br>
example log:<br>
Destination reliable queue full, dropping message; filename='/tmp/syslog-ng-00016.rqf', queue_len='6063', mem_buf_size='2097152', disk_buf_size='4194304', persist_name='afsocket_dd_qfile(stream,localhost.afunix:/dev/uds_log)'<br>
<br>
At first, I would suggest to increase the disk-buffer size.</div>

<p class="x_MsoNormal">Hi,</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">I have syslog-ng 3.32.1 running in a Debian GNU/Linux 10 (buster) with the configuration in the attachement.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">After sometime running, syslog-ng seems be unable to read from
<span style="font-family:Consolas">system()</span> and <span style="font-family:Consolas">

<p class="x_MsoNormal">Log messages from <span style="font-family:Consolas">syslog(ip(10.20.30.40) transport("udp") port(514) keep-alive(no));</span> are seen in the output folders.</p>
<p class="x_MsoNormal">Also journald logs are working fine.</p>
<p class="x_MsoNormal"> </p>
<p class="x_MsoNormal">After a reload of configuration in which what changes is this line:</p>
