Hello Amee,

Since UDP is a non-reliable transmission protocol, in case any of the
intermediary networking devices are overloaded by the transmission of
a large number of near-simultaneous messages, message loss can
occur. If you have not already, redo your tests with some
breathing space, e.g. by waiting say 10 milliseconds between each
transmission.

UDP non-reliability as the source of the losses you observe is just
an hypothesis, the real cause may be different.

Hi All,

We are using Log4j framwork and syslog-ng for logging messages on Linux.

We are using SyslogAppender of Log4j. We create sample application which has 8 
threads and one main thread which log messages into the logfile.

We are using rootLogger and patternlayout for logging message. We are also 
changing configuration file for udp connection.
If We continuously run sample application for 10 times, some log messages are 
not logged. They are missing from the log file.

We use string as parameter in log method and simplelayout to resolve this 
problem. But it is not working.

Can you please help me?

Thanks and Regards,
Amee
