Hi, Your client was disconnected from the server. It could be because of different reasons:
1. Network problems on your client. 2. Very long GC pause on the server side. I guess that you face first because you note that possible you had the network problems. In this case, the server will not able to get metrics from the client node for some time and close the connection. Data streamer operation will fail in this case because the connection was closed. However, you can try to set up failure detection as it described here is related section: https://www.gridgain.com/sdk/pe/latest/javadoc/org/apache/ignite/spi/discovery/tcp/TcpDiscoverySpi.html BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
