Hi, Thanks for the reply. Both the applications are launched in Embedded mode in Spark. I am not sure if the flag of preferIPv4Stack still matters.
Both of the applications runs perfect when they are alive. It is only when the "client application" (actually another application in server mode) closed, exit from the topology, that those error messages pop up. I couldn't understand why the server application reports such error. It should be normal that some connections disconnected.... Could you give me more detail for diagnosing the problem? -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/How-to-correctly-shut-down-Ignite-Application-tp12548p12553.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
