REST service with JSON No Response issue

Hi All,

I have created a REST service which is accepting a JSON data and processing it successfully.
However, when we provide any other JSON message not adhering to input structure of our REST service then request keep on waiting indefinitely without generating any error.
There is no log even in server and error log about this request.

But when we supply a incorrect JSON we directly get invalid JSON exception.

I am not sure how to handle a request for which there is no error generated.
ENV details:
wM IS version: 9.9

Please suggest.

Thanks,
Amit

It seems an issue with ARC google app with which I was testing my REST service.

Integration server is showing session as closed but ARC is still waiting for response.
However, when same test is done from SOAP UI, it returns an error.
