Can you show us a `syslog-ng-ctl stats` output?</div>

<div>Hi All,</div>
<div><br>
</div>
<div>I am using a Debian10 with syslog-ng 3.19.</div>
<div><br>
</div>
<div>I have a simple configuration formed by a log to a file and a log to the console "usertty(*)". Please check the attached file.<br>
</div>
<div><br>
</div>
<div><b>After some time the logging to the console stops, but the logging to the file keeps working.</b></div>
<div><br>
</div>
<div>I used strace to debug this. (strace -p <syslog-ng-pid> -yy -f -s 256 -e trace=write)
