Hi
I am using XML-RPC to communicate between two Java programs, so it is
Apache XML-RPC on both ends. I have one server and a varying number of
clients, the server sends out data to the available clients. Each client
connects to the server on startup and polls for data from the server
every 20 seconds, the polling causes the client to reconnect if
disconnected. The server keeps track of all the connected client and
checks frequently if the connected clients are alive. The server runs
thru the list of connected clients and performs a XML-RPC call to the
clients on the list, if a client is down it will not reply and the
XML-RPC will time out, this will cause the client to be removed form the
list and the server will not send any data updates to the client.
The setup is that there is a XML-RPC Client and a XML-RPC Server on both
ends.
From a log file I can see that some of the liveness calls time out
causing the client to be removed form the list only to be added to the
list after the 20 seconds have gone and the client reconnects. This is a
problem, because the client won't receive any data updates while it is
not on the list of connected clients.
I am not sure what causes these problem, but it looks like I am getting
a connection refused or connection time out. Is there any known issue
about that the web server in XML-RPC is unstable?
Thanks
Lars
