Timeout retrieving document

Question

Sometimes we get this error message when trying to get a specific document:

System.IO.IOException: Unable to read data from the transport connection: 
A connection attempt failed because the connected party did not properly 
respond after a period of time, or established connection failed because 
connected host has failed to respond. 

---> System.Net.Sockets.SocketException: A connection attempt failed because the 
connected party did not properly respond after a period of time, or established 
connection failed because connected host has failed to respond

It seems like it happens to document that are saved just recently.

If I run the query to get this document in MongoDB shell from web server it just hangs. Getting all documents including this document runs fine.

If I run the same query from another machine, everything is fine.

The only way to fix this is to change one property on this specific document from another machine.

Enviroment:

• MongoDB v2.6.3 on Windows Server 2012.
• C# / asp.net on Windows Server 2008 R2
• mongocsharpdriver version 1.9.2.
