When log files reach ~70 bytes, there seems to be an issue with flushing the buffer. Since this throws an error, the msg is not written to log either. We can try switching order or catching error?

<172.1.1.1>: msg type:RETURN_PREDECESSOR rcvd from 172.1.1.3: msg:{u'client_ip': None, u'target': None, u'msg_type': u'RETmininext> n4 ls

IOError: [Errno 4] Interrupted system call

1. start client program ie n1 python Client.py n1 \n1
2. type exit into stdin console
3. the client program should exit with this message on the screen: "bash: error reading input file: Resource temporarily available"
4. n1 any_cmd
5. mininet crashes with OSError: Broken Pipe

If a file doesn't exist on the network for a get request, we should return an error to the Client. Same for other issues.
