> Say, we have a thin client that uses some ignite service. This service
> exposes a method with an Externalizable input parameter. If cluster fails
> over after some period of successful interactions between the cluster and the
> client the following exception could be observed in cluster logs:
> {code:java}
> [2021-08-04
> 23:22:44,695][ERROR][client-connector-#114%client.ReliabilityTest%][ClientListenerNioListener]
> Failed to parse client request.
