Hello! The following has happened: Server node quit, client node stopped internal Marshaller cache, and then it was not able to use Marshaller for deserialization of message.
I'm not sure it's directly related to your case (it might just be happening in parallel with client exiting) and there's not enough logs to tell what the exact problem was. Can you show more logs? -- Ilya Kasnacheev 2017-10-19 23:16 GMT+03:00 daniels <razar...@gmail.com>: > I have 1 server and 3 client nodes,I use caching and messaging. > When I scale server node to 0,and then to 1 ,as a result some clients > cannot > reconnect. > > I have exception from client nodes > > ERROR 1 --- [er-#2%%] o.a.i.spi.discovery.tcp.TcpDiscoverySpi : Failed > to > send message: null > java.io.IOException: Failed to get acknowledge for message: > TcpDiscoveryClientMetricsUpdateMessage [super=TcpDiscoveryAbstractMessage > [sndNodeId=null, id=12qwrji-d--fsadas, verifierNodeId=null, topVer=0, > pendingIdx=0, failedNodes=null, isClient=true]] > at > org.apache.ignite.spi.discovery.tcp.ClientImpl$ > SocketWriter.body(ClientImpl.java:1246) > ~[ignite-core-2.0.0.jar:2.0.0] > at org.apache.ignite.spi.IgniteSpiThread.run( > IgniteSpiThread.java:62) > [ignite-core-2.0.0.jar:2.0.0] > 2017-10-19 13:35:09.197 WARN [um-role-service,,,] 1 --- [-#228%sys_grid%] > o.a.i.spi.discovery.tcp.TcpDiscoverySpi : Failed to reconnect to cluster > (will retry): class o.a.i.IgniteCheckedException: Failed to deserialize > object with given class loader: sun.misc.Launcher$AppClassLoader@5c647e05 > > > > -- > Sent from: http://apache-ignite-users.70518.x6.nabble.com/ >
