Resolution of the problem

We provide the "MSG_DONTWAIT" flag to the "sendto" call. By this, sendto never blocks even if internal
UDP buffers are full.

 

Linux supports that flag since 2.2 - what about RTEMS, VxWorks, Windows and the other EPICS target OSs? Have you done any research and/or run tests?
