If syslog-ng reports dropped messages in itself, increasing UDP receive
buffer will not help, as syslog-ng itself has already pulled the message.

Message drops within syslog-ng might happen because one or more of the
destinations process messages slower than the sources. If you only have file
destinations then increasing log_fifo_size() might help.
