We are using Ignite WCF service as a client to Ignite server node on another
server.
We get the following error:
Client disconnected abruptly due to network connection loss or because the
connection was left open on application shutdown.
How can we prevent the client from disconnecting as this happens consistently?
We've added Socket Timeout to the config but is there any other configuration
change that might help in this scenario?
Here is the inner exception from Ignite:
