Client loose connection after about 2 minutes

Title: Client loose connection after about 2 minutes

Version: 3.1.2

OS: Win7 64bit

Java Version: 7u5 (both 32 and 64 bit versions)

Description of Problem:

When I connect to my server from a Win xp 32 bit machine it dissconnects after about 2 minutes. giving error "connection reset by peer" or "endOfStream"

then I cant see the server any more in multiplayer list until I restart the server.

This is a new standard setup server I just downloaded, with a new generated map.

I can play on it with a client on my local win7 64 bit server machine without any problems.

I dont have any other 64 bit machines tro try and connect from.

I tryed replacing the "path" variable so I run the server on 32 bit java... (7u5)

then the server started faster.

but still the same problem with dissconnect.

Error Messages:

I dont see any error messages serverside, but it is not enough to restart the client to be able to connect again...

I have to restart the server.
