The most likely reason that another application also listens on this IP:port pair (it is possible in case of UDP and in that case the packet will be captured by the app started later)</div>

Check the output of <b>netstat -anu |grep 514</b> when syslog-ng does not capture the udp packets. You should see only one line here.</div>

In other case, you should check the debug log of syslog-ng (syslog-ng -Fevd) perhaps there is some useful information.</div>
