I have a node which is running on my machine along with a spring boot client. Client connects to node's rpc port, every thing works well but when i close my client the node crashes and i have to restart it. Why its happening is it a bug or i am doing some thing wrong. I have also deployed them on cloud and same problem happens.

It depends how you create your CordaRPCOps class.

If it is a bean, then it will call CordaRPCOps.shutdown when the client is shutdown. This is due to Spring triggering any method named shutdown on any beans by default. Therefore by not creating it as a bean, for example having a wrapper class around CordaRPCOps that is created as a bean instead will resolve this issue.

Or you can tell spring to not trigger the shutdown method by defining your bean like:

@Bean(destroyMethod = "")
public CordaRPCOps proxy() {}
