Som times a call to vos_sockSendUDP report err 183 when running Windows Sim mode.
The error only happens if SimSocketMonitoring is running and the message is sent to a multicast group no other sockets has joind. The sendSize is 0 if there is no sockets receiveing the multicast message.
Until this i fixed in SimTecc add a wokraround that sendsize == 0 && err == 183 return ok.
Workaround added
