efinitely don't want it filling up buffers with useless/old packets!)

Eric, thanks. Increasing wmem_default from 229376 to 2293760 indeed
makes the issue go away on my test bench. What's a good way to
determine the optimal value here? I assume this is in bytes and needs
to be large enough so that the SO_SNDBUF doesn't fill up before the
kernel drops the packets. How

We have an application where we are use sendmsg() to send (lots of)
UDP packets to multiple destinations over a single socket, repeatedly,
and at a pretty constant rate using IPv4.
In some cases, some of these destinations are no longer present on the
network, but we continue sending data to them
