When calling InsertOneAsync on IMongoCollection<T>, I am getting following exception. Here is what my code looks like. Since I don't need to wait for document to be inserted, I call InsertOneAsync and return. This Insert method is rapidly called multiple times.

public class MyClass{
private readonly IMongoCollection<T> myColl = MongoDbServer.GetOptionSurfaceDatabase().GetCollection<T>("MyCollection");

public void InsertData(T data)

...
}
