Here is my guess:

The connection is being closed by a NAT device between the client and 
server.  TB will ping the server every 29 minutes to avoid getting timed 
out by the server after a minimum of 30 minutes, but the NAT device 
flushes the connection quicker than 29 minutes and TB doesn't handle it 
gracefully.
