Spring Boot调用rest ws SocketTimeoutException连接超时

Question

I have developed a spring boot application, this app simply makes web service calls to another system. I have thousands of web service call tasks(Callable or supplier). Thats why I send 40 tasks per second in parallel. Target system that I send requests to has enough resource to handle thousands of request.When I start to send requests everything is fine but after a while I realize that from time to time my spring boot app get java.net.SocketTimeoutException: connect timed out

Target system is a rest web service, I used moxy implementation of JAXB in my Spring boot app while calling this target ws

Pls help me about this socket connect timeout, is there any configüration that I have to know about high volume web service call on spring boot app(embeded Tomcat)

Here is the exception full stacktrace :
