MongoDB.Driver.MongoConnectionException: Unable to connect to the primary member of the replica set: Too many threads are already waiting for a connection..

C# Driver:1.3.1
Replset:
localhost:10001 (primary)
localhost:10002 (member)

I have initReplset and add localhost:10002 to the replset,
Then I create a new connection.When I try to connect,the exception happened.

If slaveOk of this connection setting is true.

Stack:
MongoDB.Driver.MongoConnectionException: Unable to connect to any slaveOk
member of the replica set: Too many threads are already waiting for a
connection.. ---> MongoDB.Driver.MongoConnectionException: Too many threads
are already waiting for a connection.

If I modify the SlaveOK to false:

MongoDB.Driver.MongoConnectionException: Unable to connect to the primary
member of the replica set: Too many threads are already waiting for a
connection.. ---> MongoDB.Driver.MongoConnectionException: Too many threads
are already waiting for a connection.

But there is not any application access to the server.

OK,WaitQueueSize is need.
