Answer 1

I met that problem before, it was caused by the mongo database not your code, so you can enlarge the socket-timeout in your config file or call the dba.

Answer 2

I recently faced this exception. This happens if Thread is already interrupted and you are further trying to do some operation on same thread. I handled this exception by clearing the flag by using Thread.interrupted method of java.lang.Thread

Answer 3

The same error appear when you open multiple mongodb instances. Be sure that are closing the mongo clients before open a new instance. For example:

MongoClient mongo = new MongoClient ("localhost", 27017);

be sure of do: mongo.close(); I hope it helps
