RouterSocket TrySendMultipartMessage SendMultipartMessage Hangs Infinitely With Low Network Speeds

[eric-vogt-pacesetter]

I'm using a router dealer socket pair. I use NetLimiter to limit upload and download speeds to 1kbit/s SendMultipartMessage eventually hangs infinitely. I've also tried TrySendMultipartMessage with a timeout and it still hangs infinitely.

routerSocket.SendReady += (s, a) =>
{
var netMqMessage = new NetMQMessage();
netMqMessage.Append(socketIdentity);
netMqMessage.AppendEmptyFrame();
netMqMessage.Append(payload);
a.Socket.SendMultipartMessage(netMqMessage);
};
