SocketException handling request, closing client connection: 9001 socket exception [SEND_ERROR] server

HI Team ,
I am getting below exception
SocketException handling request, closing client connection: 9001 socket exception [SEND_ERROR] server

I am Using Mongo DB Server V3.0 and MongoDB Driver 2.11.

Business Case: I am working on Sync JOB. All works fine after couple of hours mentioned exception come and job stopped working.

Also, “totalCreated” connections increases rapidly during sync process(my application) but i created only one Mongo DB connection in my application code.
