@sunwuxiang Does the snippet below resolve the issue?

Which Redis vendor do you use? The actual problem that topology isn't refreshed.

Do you restart whole cluster 3-4 times?

When does the issue happen? at Redisson start moment?

Unable to reproduce. Below is the test. ```java testInCluster(client -> { for (int k = 0; k < 10; k++) { System.out.println("iteration " + k); Config config = client.getConfig(); config.useClusterServers()...

Fixed. Thanks for report

Getting same issue with the latest Kryo version ``` Caused by: com.esotericsoftware.kryo.io.KryoBufferUnderflowException: Buffer underflow. at com.esotericsoftware.kryo.io.Input.require(Input.java:221) at com.esotericsoftware.kryo.io.Input.readVarInt(Input.java:447) at com.esotericsoftware.kryo.util.DefaultClassResolver.readClass(DefaultClassResolver.java:145) at com.esotericsoftware.kryo.Kryo.readClass(Kryo.java:758) at com.esotericsoftware.kryo.Kryo.readClassAndObject(Kryo.java:869) at org.redisson.codec.Kryo5Codec$4.decode(Kryo5Codec.java:153) at org.redisson.client.handler.CommandDecoder.decode(CommandDecoder.java:454) at org.redisson.client.handler.CommandDecoder.decodeCommandBatch(CommandDecoder.java:308)...

It's a codec specific issue. https://github.com/FasterXML/jackson-databind/issues/2900 They tell that it was fixed in 2.13.0. Did you try it?
