GOAL:
Will name server resend packets to its clients if the packets get dropped or lost?
GOAL:
How messenger will respond if the packets from Name Server get deopped or lost?
FACT(s) (Environment):
Progress 9.x
FACT(s) (Environment):
WebSpeed 3.x
FIX:
The communication between name server and its clients including messenger is UDP, UDP is a connectionless protocol. If a packet from the NameServer to a messenger is lost, the NameServer will not know that the messenger never received the packet, and so the NameServer will never resend the packet.
Once the messenger requests a broker from the NameServer, it waits up to 12 seconds to receive a reply from the NameServer. If the messenger never receives a reply from the NameServer, it will display following message in the browser.
Connection failure for host localhost port 5162 transport UDP. (9407)
Content-Type: text/html
WebSpeed error from messenger process (6019)
Msngr: the specified service name does not exist or has a bad format.
