SUMMARY
SYMPTOMS
Your Remote Procedure Call (RPC) server's context_rundown() function is
called when your RPC client is inactive for more 5 minutes and uses either
ncadg_ip_udp or ncadg_ipx as the communication protocol sequence.
CAUSE
This behavior is by design. When this timeout is reached, your RPC server
assumes that the client is no longer available.
RESOLUTION
To avoid your RPC server from invoking your context_rundown() function,
your RPC client needs to issue remoted function calls to your server
periodically so that it does not go idle for more than 5 minutes.
The context handle time-out described in the following Microsoft Knowledge
Base article concerns RPC communication using ncacn_ip_tcp not
ncadg_ip_udp.
