Subject Re: Request for help: Log messages are not logged properly

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

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